RESUMEN

Reference values of the number and proliferation index (PI) of stromal fibroblasts in children have been presented: CFUf per 10(5) = 57.0 +/- 4.1; CFUf in 1 microliters = 85.4 +/- 8.1; PI = 1.7 +/- 0.05. It has been shown that the number of stromal fibroblasts increases in the prepubertal period, especially in girls. No relationship has been observed between CFUf and the number of platelets and megakaryocytes in the children investigated. Correlation has been established between the number of bone marrow clonogenic fibroblasts and the amount of myelokaryocytes and the number of granulocytic-macrophagal precursors in the bone marrow.
