The invasive capability of human lung great cellular xancerous PG cell on reformed basement membrane and Inhibition of synthetic peptides

Objective To study the invasive capability of human lung great cellular carcinoma PG cell on reformed basement membrane in vitro and inhibition of anti-tumor synthetic peptide. Methods Use tran- swell culture cell. Results When optimun PG cell was affected for lob by chemotatic reagent, invasive cell could reach the number range of statistics; 25-100 ug/ml RGD-YIGSR and most of the derivative could inhibit the invasion of PG cell on reformed basement membrane incubating w...
