Platelet count is positively correlated with white cell count and red cell count

Platelet count is positively correlated with the white cell count in healthy males aged 20-68 years (p less than 0.002) and in healthy medical students of both sexes aged 18-22 years (p less than 0.0001). Platelet count is also positively correlated with red cell count in healthy males (p less than 0.02). Red cell count is positively correlated with white cell count in the older healthy males (p less than 0.02) and in the male medical students (p less than 0.003). These findings provide support for the concept of a single hormone-dependent pluripotent stem cell whose effect is seen concomitantly in all circulating blood cells. The white cell count and platelet count correlation is less significant in the males aged 35 or above which may represent the development of pathological mechanisms.
