Cell Factor is a start-up company from Kyoto University that is working to find cures for intractable diseases using regenerative medicine.

With advances in growth factor production through research at Kyoto University and the latest stem cell therapies, the long-standing dream of physicians and clinicians to successfully treat various illnesses and pain has taken shape, as we have created "Cell Factor Inc.".

We want to maximize the effects of cells, growth factors, scaffold materials, physical environment, and DDS, among others that support regenerative medicine to realize new ideas and approaches that not only cure diseases but also prevent them. We want more of life's precious moments to be spent happily and joyfully, rather than be disrupted by illnesses.

As a first step toward this goal, we are committed to "conquering an intractable disease, osteonecrosis of the femoral head", and ensuring well-being through regenerative medicine.

* Well-being: a state of happiness in which everything is fulfilled physically, mentally, and socially. Sustained happiness.

Origin of the logo design

Cell X (fusion) Factor

The "X" represents our desire to invent new chemical reactions and realize unknown possibilities by combining the passion (ambition) and professionalism (expertise).

The symbol represents a stem cell full of vitality, encompassing all three elements.


Regenerative Medicine
