With that, let me turn the call over to Yehiel Tal, Chief Executive Officer of CollPlant Biotechnologies. Please go ahead, sir.
Yehiel Tal: Good morning, everyone. We are very pleased to have you join us today on CollPlant's very first investor conference call to discuss the 2022 financial results and corporate developments. Since this is the first call with investors, we wanted to remind you about the mission of our company. CollPlant is developing and delivering collagen technology and regenerative medicine products to improve and prolong life. And now, imagine a future where there will be an unlimited supply of spare parts for the human body, including life-saving organs. And also imagine that in the future medical treatment will be tailored for the individual characteristics of each patient. And then also imagine that drugs will be developed without the need for animal testing.
We at CollPlant aspire to become the leaders in regenerative medicine, helping people live longer and better, and creating improvements in science through our regenerative technology. Since being a Nasdaq listed, in 2018, we have drawn on the collective strength of our company management in regenerative medicine, medical devices and engineering, as well as our strong IP position, human capital and partnerships to derive the company's value and innovation and become market leader in regenerative anesthetic medicine. Collagen is the primary scaffolding molecule in the body's connective tissues and organs. And it is our goal to become global leader in regenerative medicine by applying our non-animal-derived recombinant human collagen, or rhCollagen, to novel medical and aesthetic products.
Now, let's move to recent developments that relate to our novel programs that rely on rhCollagen technology. The first category that we are applying our technology is in aesthetic medicine with our dermal filler product candidates. Our long-term collaboration with AbbVie to develop a paradigm shift in regenerative dermal and soft-tissue filler continues to move forward according to plan. Per the agreement, CollPlant has the potential to receive additional milestones and option payments regarding the two products that we are developing, and we'll receive royalties on any product sales should we obtain approval. AbbVie continues to advance the filler program, and CollPlant expects that the first of these milestones could be achieved in 2023. In addition, we are moving forward with a third-generation photocurable dermal and soft-tissue filler.
Our goal with the development of this filler is to create a product with three capabilities; lifting capacity, regeneration of new tissue, and (ph) capabilities. Recently, we generated additional supporting data from a 12-months pivotal preclinical study of this filler, demonstrating superior tissue regeneration, lifting capacity, and volume retention compared to the industry gold standard. This promising result combining the regenerative properties of collagen and the advantages of photocuring technology position CollPlant's product candidate as a revolutionary platform technology with the potential to create a paradigm shift in the evolving medical aesthetic market. We believe that this third-generation filler has the potential to be highly competitive by providing both refined and natural-looking aesthetic results as well as uniquely regenerative long-term benefits.

CollPlant has granted its global pharmaceutical partner, AbbVie, the right of first negotiation to obtain a worldwide exclusive license to this product candidate. Our second area of focus is regenerative aesthetics with our regenerative breast implant program. Earlier this year, we announced positive results from a preclinical study evaluating our regenerative implants in a large animal model. Results from this study demonstrated progressive stages of tissue regeneration after three months, as highlighted by the formation of maturing connective tissue and neovascular networks within the implants with no adverse events reported. No regenerative breast implant currently exists in the market, and these implants would be the first of their kind also having beneficial regenerative properties.
Importantly, since these implants are made of our rhCollagen and other biomaterials versus animal-derived collagen, there is less chance of rejection by the body or what is known as acute rejection. According to the U.S. Food and Drug Administration, approximately 350,000 Americans have reported adverse events involving breast implants between 2009 and 2019. Reports range from autoimmune symptoms to breast implant-associated anaplastic large cell lymphoma. CollPlant's implants are expected to regenerate breast tissue without eliciting the immune response, and thus may provide a revolutionary alternative for both aesthetic and reconstructive procedures, including postmastectomy for cancer patients. Later this year, we plan to initiate another study in large animals with commercial-sized implants to generate additional safety data in support of commercialization.
And we look forward to reporting results of that study. We also made a decision to strategically expand into personalized medicine. And we signed a collaboration agreement, in November 2022, with Tel Aviv University and Sheba Medical Hospital for our gut-on-a-chip program. Our agreement with these two research institutions is to co-develop bioprinted human intestine model for drug discovery and personalized treatment of ulcerative colitis. The 3D bioprinted model is designed to emulate the human intestine tissue in order to allow medical professionals to identify drug targets and personalized therapeutic responses that can lead to improved patient outcomes. We expect that this approach could be groundbreaking improvement over existing use of animal models.
CollPlant will have the right to commercialize the product once ready to market. Now, let me turn to our commercial portfolio of BioInks, which is another program of ours that falls within our focused area of regenerative medicine. We expanded our commercial portfolio of collagen-based BioInks with two new products, including Collink.3D 90 which offers increased mechanical properties, and Collink.3D 50L with our first BioInk available in powder form to provide enhanced operational flexibility. Our BioInk platform, which was established in 2021 with the launch of Collink.3D 50 allows our biopharma and academia customers to streamline their process of new product development by utilizing animal free alternatives that delivers improved biofunctionality, safety, and reproducibility.
CollPlant remains engaged in partnering discussions with several industry leaders and academic institutions interested in the company's technology and expertise in 3D bioprinting to develop therapeutics and medical applications. We are confident that our collaboration with a worldwide pharmaceutical leader as well as other numerous collaborations and partnership agreements has validated our technology and its multiple areas of applicability. We have also made strides in developing a proprietary aseptic process to mass produce sterile collagen. The sterile collagen will serve as an ideal substrate for stem cells, induced pluripotent stem cells, and all kinds of primary human cells. It will also address production processes where collagen as major constituent should be sterilized.
And now I will turn the call over to our Deputy CEO and Chief Financial Officer, Eran Rotem to provide a recap of our financial results, Eran?
Eran Rotem: Thank you, Yehiel. Good morning, everyone. I will now review our financial results for the full-year period ending December 31, 2022. GAAP revenue for the year 2022 was $299,000 and included income from sales of the company's BioInk and rhCollagen. Revenues decreased by $15.3 million, compared to $15.6 million for the year ended December 31, 2021. The revenues in the year 2021 were mainly derived from the $14 million upfront payment from AbbVie in return for the rights CollPlant granted to AbbVie. As we said previously, according to the agreement with AbbVie, CollPlant has the potential to receive additional milestone payments based on product development milestone suite. Note that in 2022, CollPlant did not receive any such payments, and CollPlant expects that the first of these milestones could be achieved in 2023.
GAAP cost of revenue for the year ended December 31, 2022 was $400,000, a decrease of 80% compared to $2 million in the year 2021. Cost of revenue includes mainly the cost for the company's rhCollagen-based BioInk products and royalties to the Israel Innovation Authority, or IIA for our sales. The decrease in cost of revenue in the amount of approximately $1.6 million is mainly comprised of the decrease of approximately $460,000 in royalty expenses to the IIA and a decrease in the amount of approximately $1 million relating to BioInk and rhCollagen sales. GAAP gross loss for the year-ended December 31, 2022 was $101,000 compared to gross profit of $13.6 million in the year-ended December 31, 2021. GAAP operating expenses for the year ended December 31, 2022, was $17 million compared to $13.6 million in 2021.
The increase in expenses amounting to approximately $3.4 million is mainly comprised of $1.4 million in research and further development activities including process development. And these costs are mainly associated with the successful development of aseptic process. So, now we can supply sterile collagen products to our business partners, and $1 million in employee salaries and share-based compensation including recruitment of new employees for development of new product in 3D bioprinting in medical aesthetics. And lastly, an increase of $900,000 in general and administrative expenses related to employees and director's salaries and insurance policy expenses. On a non-GAAP basis, the operating expenses for the year ended December 31st 2022 was $15.2 million compared to $11.9 million for the year ended December 31st 2021.
Non-GAAP measures exclude certain non-cash expenses. GAAP financial income net for each of the years ended December 31st 2022 and 2021 totaled $172,000. Financial income net is mainly attributed to interest received from the company's short-term cash deposits. GAAP net loss for the year ended December 31st 2022 was $16.9 million, or $1.53 basic loss per share compared to a net income of $237 or $0.02 income per share for year ended December 31, 2021. Non-GAAP net loss for the year ended December 31, 2022 was $15.2 million. Or, $1.37 basic loss per share compared to $1.9 million income or $0.19 basic income per share for the year ended December 31st 2021. Cash and cash equivalents and short-term deposits as of December 31, 2022, was $29.7 million.
Cash used by operating activities during the year 2022 was $13.7 million compared to $2.5 million cash provided by operating activities in the year 2021. Cash provided by investing activities during the year 2022 was $28.9 million compared to $31.6 million in cash used in the year 2021. The change is mainly attributed to repayment and investment in short-term cash deposits. Cash provided by financing activities during the year 2022 was $1.9 million compared to cash provided in financing activities of $38.8 million in the year 2021. In 2022, the company received $1.9 million mainly from the exercise of warrants into the company's shares. In 2021, the company executed a registered director offering which resulted in net proceeds of $32 million.
And realized proceeds in the amount of additional $6 million from exercise of options and warrants. This now concludes the financial summary. Operator, I believe that we can now open up the call for questions.
