The purpose of this study is to evaluate the effect of conditioned media (CM) collected from human amniotic fluid-derived stem cells (hAFSCs) on in vitro wound healing and on expression change of MMP-1 and procollagen 1A by ultra-violet A (UVA) irradiation. The conditioned media (CM) were collected from hAFSCs cultured with DMEM/F-12 serum free media.(More)
The electrophysiological actions of phencyclidine (PCP) and the sigma agonist 1,3-di(2tolyl)guanidine (DTG) were examined in the cerebellum of urethane-anesthetized rats. The object of the study was to determine if PCP and sigma agonists shared a common mechanism of action. The cerebellar Purkinje neuron was chosen because it has sigma receptors but not(More)
