Abstract:
The growth of fibroblasts on the acellular dermal matrix (ADM) was studied. The fibroblasts isolated from the skin of an adult New Zealand Rabbit were cultured in vitro and identified subsequently. After the cells were inoculated on the ADM as seeds, the adhesion rate and the growth ability were examined, and cellular morphology was assayed with DAPI fluorescent staining and Scanning electron microscope (SEM). The possibilities of applying ADM as cells carrier or deliverer in the field of transplantation were evaluated. The result revealed that pure fibroblasts were isolated through the specific method. Skin fibroblasts could adhere to ADM easily, and the adhesion rate was 96.78%, displaying no significant difference (P > 0.05) when compared with that rate of the control holes. The cells on the scaffolds and those on the control holes showed similar growth tendencies, but the activity of the former was lower (P < 0.01). The integral nucleus with blue fluorescence could be observed on the ADM under fluorescence microscope. The number of fibroblasts scaled up with the cultured time, The results of SEM showed that the state of cell was good and the fibroblasts were fused into a layer after being cultured for 5-10d. So rabbit fibroblasts can attach, survive, grow and proliferate on the ADM in a healthy way. It is entirely possible to use ADM as an appropriate scaffold material for the culture of fibroblasts and as a material for transplantations.
