Figure 3. Dermal blood vessels are reduced in CRABP-IIknock-out mice. (A) Representative images and (B) bar graph showing semiquantitative evaluation of CD31-positive dermal small vessels in young/adult and old wild-type (WT) and CRABP-II knock-out (KO) mice (n=10 young/adult and n=10 old WT, n=10 young/adult and n=10 old CRABP-II KO). Scale bar: 100µm. Values are group mean ± SEM. t-Test: * indicates p<0.05.
