Quantification of angiogenesis by morphometric analysis

	Number of vessels/field		Vascular area(μm2)
Days postimplantation	WT	PAFR-KO	WT	PAFR-KO
7	17±2	25±2*	330±19	400±23*
10	17±1	22±2*	453±28	567±34*
14	16±1	21±1*	458±33	609±63*

Data represent mean±s.e.m. The number of vessels was obtained by counting 45 fields (three repetitions of 15 fields) of sponge implants of WT and PAFR KO mice. The vascular area was the sum of lumen area divided by the number of vessels.

^*P<0.05, significant difference between the values of PAFR-KO and WT mice.
