Arizona Tribune - Cell Source Presented Its Breakthrough Developments for Mismatched Donor Stem Cell and Organ Transplants and Off-the-shelf CAR-T Cell Therapy at the LD Micro Invitational Conference in Los Angeles This Week

NEW YORK, NY / ACCESS Newswire / May 21, 2026 / Cell Source, Inc. (OTC PINK:CLCS) ("Cell Source" or the "Company"), a leading innovator in immune tolerance management, recently presented its plans to expand its clinical program for haploidentical (partially mismatched donor) stem cell (e.g. bone marrow) transplants under low levels of immune suppression and avoiding GvHD and viral infections, to include both partially mismatched kidney transplants, without the need for ongoing immune suppression post transplantation, and also off-the-shelf (donor derived) CAR-T cell therapy. The company also is planning an uplist to the NASDAQ exchange.

Quote from CEO Itamar Shimrat:

"Cell Source is excited to share our compelling results, especially in light of the recent surge in high value clinical stage oncology acquisitions. We feel that the timing for our plans to uplist to a senior exchange and fund our clinical expansion program dovetails perfectly with the current trend of major players who are acquiring early clinical stage oncology companies with compelling, distinctive clinical candidates"

About Veto Cell Technology

Cell Source's Veto Cell technology is the brainchild of Professor Yair Reisner, a world-renowned expert in immune tolerance management who pioneered mismatched bone marrow transplants. The company's technology, exclusively licensed from The Weizmann Institute of Science in Israel, is being developed to create safer, donor-derived CAR-T therapy and improve the accessibility of stem cell transplants and organ transplants.

About Cell Source, Inc.

Cell Source, Inc. (OTC:CLCS) is the worldwide, exclusive innovator of Veto Cell-based cellular therapy and immunotherapy platform technologies designed to provide safer and more accessible stem cell (e.g. bone marrow) transplantation and improve the treatment of blood cancers such as leukemia, lymphoma and multiple myeloma. In addition, its Veto Cell platform is being developed to reverse sickle cell disease and other non-malignant genetic blood disorders and to durably treat auto immune diseases such as type 1 diabetes. The Company is developing a Veto Cell CAR-T platform which could potentially enable CAR-T therapy to be used in donor-derived (allogeneic) settings with increased safety, efficacy, and persistence. Cell Source's Veto Cell technologies are also being developed to facilitate safer, donor mismatched organ transplants (e.g., kidney and liver) and also avoid the current need for life-long daily immune system suppression.

The Company is focused on transitioning this allogeneic Veto Cell platform into additional clinical trials in order to develop safe and curative cell therapy treatments (such as stem cell transplants) from mismatched donors as well as safe, durable, and efficacious "off-the-shelf" immunotherapy and immuno-oncology products.
