The invention relates to a method for implementing subcutaneous tissue regeneration by using a tissue engineering technology, belonging to the field of tissue engineering. Mesenchymal stem cells in waste healthy infant umbilical cord are extracted and separated, and animal source-free serum safely amplified in vitro is mixed with a degradable gel biological material to form a subcutaneous injection complex, wherein the complex is mainly applied to senescence and hollowness filling, cicatrix repair, auxiliary repair of large-area skin coloboma of burn department and treatment of diabetic sole ulcer. The mesenchymal stem cells from the umbilical cord have good activity, have no immunological rejection and avoid ethical limitation; and the reinjection operation of the complex is simple, the treatment is remarkable after the treatment, and timeliness of clinical treatment can be realized.
