HGF modulates actin cytoskeleton remodeling and contraction in testicular myoid cells [PDF]

open access: yes, 2015
The presence of the HGF/Met system in the testicular myoid cells was first discovered by our group. However, the physiological role of this pathway remains poorly understood. We previously reported that HGF increases uPA secretion and TGF-β activation in
