About osteonecrosis of the femoral head (ONFH)
ONFH is a refractory disease that causes femoral head collapse, pain, limitation of hip motion and gait disturbance.
＜Age at presentation＞
30 years of age
The main cause of the disease is the use of steroids.
ONFH is a destructive disease of the hip joint caused by a critical decrease in the vascular supply to the femoral head.
Disadvantages of artificial joints
Disadvantages of artificial joints
Joint preserving regenerative therapy
has been the ultimate therapeutic goal for ONFH.
Attention needs to be paid to a possible rapid increase
in steroid-associated ONFH after the COVID-19 pandemic

Regenerative therapy for ONFH
Regenerative medical products
based on research results
Research and development of high-spec adipose tissue-derived stem cells, growth factors, exosomes, and cellular pads. By ensuring the fixation of growth factors and cells at the time of injection, it is possible to maintain their effects for a longer duration.
Use of novel surgical devices and the development of novel devices for precise cell injection (patent pending). Since the skin incision made during the treatment is only 1 cm long, day treatment is possible. Moreover, we are developing products using environmentally friendly materials.
We support wider use of “regenerative medicine” using cells and growth factors. We provide complete support for clinical management, branding, and technical guidance to both insured and uninsured patients.
The regenerative technologies developed for ONFH will be applied to the treatment of osteoarthritis of the knee, bone fractures, and osteoporosis.

First, it is applied to treatment based on the Regenerative Medicine Act. Subsequently, we aim to promote the use of the system through insurance.
The Envisioned Future
Cell Factor will not only enhance the well-being of patients with “osteonecrosis of the femoral head” but also of those with various other diseases and maladies.
Application has already started for developing the preventive treatment against aging. It is difficult to secure developers for research in the treatment of intractable and rare diseases since this field may not in line with corporate interests. Cell Factor will overcome this challenge and continue to safely provide the regenerative medicine needed by the patients and society.
