Area in percent showing hair growth stimulation
FIG. 4. T h e number of female C57BL/6J mice showing varying amounts of hair
growth stimulation (from Argyris and Trimble, 1964a).
mouse shows its own peculiar pattern of spread of hair growth stimulation
(Fig. 5) (Argyris and T r i m b l e , 1964a). Clearly, the fact that the variation in the time of appearance, amount, and pattern o f hair growth
stimulation persists in inbred mice of the same sex and age, and bearing
FIG. 5. Pattern of hair growth stimulation in wounded female C57BL/6J mice.
The diagram indicates the pattern of hair growth stimulation for 2 mice separated
by the black vertical line. Read drawings from left to right. Black area represents
growing hair follicles which have erupted through the skin; stippled area represents
growing hair follicles which have n o t yet erupted through the surface of the skin;
and white area represents resting hair follicles (from Argyris and Trimble, 1964a).
