摘要:
PURPOSE: A medical composite biomaterial containing collagen and hyaluronic acid derivatives is provided to ensure durability and to effectively treat degenerative arthritis and cartilage damage. CONSTITUTION: A composition contains collagen and hyaluronic acid or a derivative thereof. The collagen is type I collagen and is derived from human umbilical cord. The hyalruonic acid derivative is prepared by crosslinking hyaluronic acid using BDDE(1,4-butandiol diglycidyl ether). A medical composite biomaterial contains the composition. A chondrocyte therapeutic agent contains the stem cells, collagen, and hyaluronic acid or the derivative. The stem cells are cultured in a container coated with cell adhesion proteins using a medium for culturing the stem cells. The cell adhesion protein is the collagen, gelatin, fibronectin, laminin, or poly-D-lysine. A composition for an injection for treating damaged cartilage contains the chondrocyte therapeutic agent. A method for treating damaged cartilage comprises a step of administering the composition to a patient.본 발명은 의료용 복합 생체소재에 관한 것이다. 보다 상세하게는, 본 발명은 콜라겐 및 히알루론산 유도체를 포함하는 의료용 복합 생체소재에 대한 것이다. 또한, 상기 생체소재 및 포유류의 탯줄 유래 줄기세포를 이용한 연골세포치료제에 관한 것이다. 이러한, 생체소재는 면역 반응을 야기하지 않고, 내구성이 우수하며, 이러한 생체소재와 줄기세포를 포함한 연골세포치료제는 관절경을 이용한 시술이 가능하여 환자의 고통을 줄여줄 뿐만 아니라 효과적으로 퇴행성 관절염 및 연골 손상을 치료할 수 있다.
