Learn more


RegStem is an innovative biotechnology and biopharmaceutical company repurposing and creating new drugs in the regenerative medicine fields.

Based at Paris Biotech Santé, a life science incubator in the center of Paris ( ) the company is engaged in the research, development and licensing of innovative molecules for use in Human therapies. Its mission is to bring to the market as well as license to pharmaceutical companies after clinical trials new pro regenerative drugs.

Our promises

Repurposing of marketed drugs

RegStem is repurposing drugs in the regenerative medicine fields. In particular the company will focus on the reconstitution and repair of bone marrow during acute aplasia and skin after scar by stimulating the stem cells but also controlling their differentiation and their environment.

Development of proprietary molecules

RegStem is also creating new molecules based on the screening of libraries that will be used in chronic diseases that impairs regenerative capacities of skin and muscles.
