Abstract
ObjectiveTo explore the approaches of porcine bladder smooth muscle cells separation, culture, proliferation and identification in vitro, and provide evidence for tissue engineering bladder establishment.
MethodsThe bladder were obtained from 4 Diannan small eared pigs, and the bladder smooth muscle cells were isolated by trypsin digestion and cultured by DMEM/F12 medium. Cell growth and proliferation were observed, and the bladder smooth muscle cells were identified by immunohistochemical staining.
ResultsThe cells cultured in vitro appeared confluent and were in long shuttle form with the typical morphology of "valley and peak" . These cells were in accord with the morphological characteristics of smooth muscle cells by HE staining, and they were positive for smooth muscle actin staining.
ConclusionsSmooth muscle cells of the porcine bladder are available through this approach which can be used in the construction of tissue engineered bladder.
