ABSTRACT
To investigate the possibility of constructing composite skin, keratinocytes were cultivated in vitro on the epidermal surface of cell free dermis prepared from pig skin.Keratinocytes grown on the dermal matrix were released at selected time points, followed by determining the proliferative capacity with cell number quantity and cell proliferation test. Cells attaching to the dermal matrix after it were seeded for 1 and 2 weeks were observed with histological section HE staining and electron microscopy scanning. Results showed that the number of keratinocytes was markedly increased with culture time. They maintained their proliferative potential after they were seeded on acellular xeno dermal matrix and reached a confluent monolayer or 3 to 6 layers at the 1st and 2nd week after seeding. The data showed that a living composite skin combined with keratinocytes and acellular dermal matrix could be successfully prepared in vitro.
