Implanted SKPs secrete growth factors and differentiate into blood vessel in vivo. Immunostaining of DiI and growth factor bFGF, VEGF and blood vessel maker vWF, α-SMA in implantation site of IBZ. Brain sections were immunostained for ((a), (b)) bFGF, VEGF (green) or for ((c), (d)) vWF, α-SMA (green). Arrowhead shows DiI positive cells (red) that were colocalized with bFGF and VEGF (green). Scale bars, 10 μm.
