Business Details

This segment manufactures and sells five products to medical institutions: JACE (Autologous Cultured Epidermis) for skin, JACC (Autologous Cultured Cartilage) for cartilage, Nepic (Autologous Cultured Corneal Epithelium) for cornea, Ocural (Autologous Cultured Oral Mucosal Epithelium) for cornea, and JASMIN (Melanocyte-containing Autologous Cultured Epidermis) for skin. The business is based on the autologous transplantation method, in which a patient's own cells are cultured and transplanted, and provides insurance-covered products that have received manufacturing and marketing approval from the Ministry of Health, Labour and Welfare. In FY2026 (ending March 2026), this segment accounted for approximately 62% of total company revenue of ¥2,183 million, making it the core segment.

Recent Overview

Sharp increase in JACC orders toward year-end following insurance listing for knee osteoarthritis, but overall revenue declined

Regenerative Medicine Products Business revenue for FY2026 (ending March 2026) was ¥1,354 million (down 9.3% year on year). This was impacted by a continued decline in the number of burn patients and sluggish growth in new patients in the corneal field. On the other hand, following the insurance listing of JACC for knee osteoarthritis in January 2026, the number of contracted facilities expanded to 125, and a record monthly high of 30 cases was achieved in March. JASMIN also built a foundation for revenue growth by expanding its network of participating facilities to 42. Segment profit fell sharply to ¥78 million from ¥219 million in the prior period.

Key Products

product
JACE (Autologous Cultured Epidermis)

The primary indication is severe burns, with expanded indications for giant congenital melanocytic nevus and epidermolysis bullosa (dystrophic and junctional types). Insurance reimbursement limits are 40 sheets for burn treatment (50 sheets when medically necessary), 30 sheets for giant congenital melanocytic nevus, and 50 sheets for epidermolysis bullosa. In FY2026 (ending March 2026), the number of burn patients continued to decline, but orders showed a recovery trend in the fourth quarter.

product
JASMIN (Melanocyte-containing Autologous Cultured Epidermis)

Indicated for vitiligo that is ineffective with or not amenable to non-surgical treatment. In FY2026 (ending March 2026), the number of participating facilities expanded to 42, and orders were secured from new facilities toward the end of the fiscal year. Although it took time to prepare for introduction at some medical institutions, progress was made in building a foundation for revenue growth.

product
JACC (Autologous Cultured Cartilage)

The primary indications are traumatic cartilage defects and osteochondritis dissecans of the knee joint. On May 13, 2025, approval was obtained for an expanded indication to knee osteoarthritis, which was listed for insurance coverage effective January 1, 2026. The number of contracted facilities expanded to 125 nationwide, and a record monthly high of 30 cases was achieved in March 2026. The product's positioning has shifted to that of the main product for medium- to long-term growth.

product
Nepic (Autologous Cultured Corneal Epithelium)

Indicated for limbal stem cell deficiency. In FY2026 (ending March 2026), orders declined due to sluggish growth in new patients at existing facilities. In collaboration with Nidek Co., Ltd., which handles sales, the company is promoting the development of new facilities and awareness of treatment among potential patients, and has achieved adoption at several leading new facilities nationwide with corneal transplant experience.

product
Ocural (Autologous Cultured Oral Mucosal Epithelium)

The world's first regenerative medicine product capable of treating bilateral limbal stem cell deficiency using oral mucosal epithelial cells. In FY2026 (ending March 2026), as with Nepic, orders declined due to sluggish growth in new patients at existing facilities. The company continues to develop new facilities in collaboration with Nidek.

Growth Drivers

  • Market expansion and increase in contracted facilities (125 facilities) driven by the insurance listing of JACC for knee osteoarthritis (January 2026), along with a record high in monthly orders
  • Building a foundation for revenue growth through the expansion of JASMIN's participating facilities (42 facilities) and securing orders from new facilities
  • Future expansion of the product lineup and overseas development through the application for manufacturing and marketing approval of allogeneic cultured epidermis (Allo-JaCE03) (March 2026)
  • Progress in the joint development of new knee-field products with Teijin
  • Development of new facilities and promotion of treatment awareness among potential patients for corneal field products in collaboration with Nidek

Risks

  • Structural cost challenges due to the nature of the autologous transplantation method, which requires individualized manufacturing for each patient and makes it difficult to achieve economies of scale
  • Slowing demand due to a decline in and saturation of the target patient population for existing indications such as burns, giant congenital melanocytic nevus, and epidermolysis bullosa
  • Continued sluggish growth in new patients and declining orders at existing facilities for corneal field products (Nepic and Ocural)
  • Risk that the pace of adoption of JACC for knee osteoarthritis following insurance listing may fall short of expectations
  • Risk of changes in the regulatory environment, including discussions on reviewing the conditional and time-limited approval system
