The recruitment of exogenous endothelial progenitor cells in lung tumor model of nude mice.

Background And Objective: Endothelial progenitor cells (EPCs) play an important role in hypoxia-triggered tumor vasculogenesis. However, the homing of exogenous EPCs in tumors is still unclear. In this study, we investigated the recruitment of exogenous EPCs in human lung adenocarcinoma model of nude mice.

[Effects of mineral trioxide aggregate and calcium hydroxide on the proliferation and differentiation capacity of pulp cells of primary teeth].

Objective: To investigate the effects of mineral trioxide aggregate (MTA) and calcium hydroxide on the proliferation and differentiation capacity of pulp cells of primary teeth.

Methods: Pulp cells were isolated from the retained primary teeth without apparent root resorption and cultured. The cells of 4 - 8 passages were used in the study.
