[The differentiation factor in the bone marrow and blood serum of healthy subjects and in acute leukemia].
Abstract
The factor of differentiation--i.e. systemic morphogen of connective tissue (SMCT)--have been discovered in bone marrow and blood serum of healthy humans. SMCT calls forth the differentiation of mesodermal cell types in early embryonic amphibian cells. These cell types are the following: notochords, muscles, mesothelium, blood cells, mesenchyme. Under the influence of the punctates of bone marrow the frequency of muscle and blood cell appearance is not constant, which might be the consequence of the individual variability of SMCT. Under the influence of bone marrow and blood serum in patients with acute lymphoblastic, monoblastic and myelomonoblastic leukemia the embryonic cells differentiate only into atypical epidermis, which proves the absence of the SMCT activity in the sources used. In some cases under the influence of bone marrow from patients having the same disease the early embryonic cells differentiate into mesodermal cell types, which normally appear under the low concentration of SMCT. This was observed however only in those cases when bone marrow or blood serum have been taken from patients in the state of remission. In patients with remission the correlation is observed between the activity of factor of differentiation in bone marrow and that of blood serum.
