TreeFrog Therapeutics mass-produces stem cells and organoids to enable the development of cell therapies for all.

Our technology

Stem Cell Mass-Production

A unique proprietary technology to boost your cell therapy from stem cells production to grafting.

Outstanding quality to support industrial cell therapies

At the heart of TreeFrog is the desire to rise up to the challenge of industrial production, without compromising quality. Maxime Feyeux’s first and foremost scientific work has been on the topic of pluripotent stem cells genomic integrity.


Our technology enables the delivery of younger cells to mitigate mutational risks. A third party quality control guarantees the genomic integrity of the cell banks we provide.

Stem-cell based organoids made easy

For half a decade, Treefrog’s cofounders have been working on making organoids from pluripotent stem cells derived populations. Suddenly organoids are becoming fashionable. This is good news for us and good news for you : ln addition to delivering cell banks, we are capable of mass­producing stem-cell derived organoids.


At TreeFrog we believe there is no such thing as barriers between disciplines. Physics and Biology are just beautiful words, and with beautiful words one builds beautiful worlds. Come and join us into the beautiful world of biophysical medicines.

TreeFrog Therapeutics : stem cell banking services & stem cell organoids for cell therapy

TreeFrog Therapeutics is a French stem cell company aiming at supporting the advent and industrial development of stem cell therapies. Our team has developed a unique technology for stem cell culture. Tree Frog Therapeutics provides human induced pluripotent stem cells generation, amplification and banking services for research and therapeutic applications. Our human ipsc banks are provided together with third-party control data about the genomic integrity of the cells. To learn more about our custom stem cell services for research and cell therapy (iPSC generation, iPSC bank amplification, …), please contact us. As a stem cell supplier, we also deliver in vitro stem cell 3D models : stem cell organoids. Such stem cell 3D tissues are more physiologically relevant than stem cell spheroid cultures. Based on MSC or iPSC cells, our organoids are suitable for preclinical proof-of-concept studies, toxicology screening and transplantation studies in the context of regenerative medicine programmes.
