...Vincenzo Cavalieri; Rosa Guarcello; Giovanni Spinelli In the indirect developing sea urchin embryo, the primary mesenchyme cells (PMCs) acquire most of the positional and temporal information from the overlying ectoderm for skeletal initiation and growth. In this study, we characterize the function...
