Abstract: | Mice lacking the pro-adhesive matricellular protein connective tissue growth factor (CTGF/CCN2) display an embryonic lethal
phenotype due to defects in bone and cartilage. However, the specific role of CCN2 in skin development is unknown. Here, we
generated mice deleted for CCN2 in the entire body (using a cre/lox system in which CCN2 is deleted in the entire body due
to the presence of a constitutively expressed cre recombinase). We found that CCN2 was not required for the development of
skin as defined by skin thickness measurements, trichrome staining and immunostaining with anti-CD31 (to detect endothelial
cells) and anti-α−SMA (to detect smooth muscle cells and pericytes) antibodies. Thus, although recently we have shown that
CCN2 is required for fibrogenesis in postnatal mice, CCN2 is not required for skin development during embryogenesis. |
