Evolving insights into the synergy between erythropoietin and thrombopoietin and the bipotent erythroid/megakaryocytic progenitor cell

Experimental Hematology
T Papayannopoulou, K Kaushansky

Abstract

Although the synergy between erythropoietin and thrombopoietin has previously been pointed out, the clonal demonstration of a human bipotent erythroid/megakaryocytic progenitor (MEP) was first published in Experimental Hematology (Papayannopoulou T, Brice M, Farrer D, Kaushansky K. Exp Hematol. 1996;24:660-669) and later in the same year in Blood (Debili N, Coulombel L, Croisille L, et al. Blood. 1996;88:1284-1296). This demonstration, and the fact that both bipotent and monopotent erythroid or megakaryocytic progenitors co-express markers of both lineages and respond to both lineage-specific transcription factors, has provided a background for the extensive use of MEP assessment by fluorescence-activated cell sorting in many subsequent studies. Beyond this, the demonstration of shared regulatory elements and the presence of single mutations affecting both lineages have inspired further studies to decipher how the shift in transcription factor networks occurs from one lineage to the other. Furthermore, in addition to shared effects, erythropoietin and thrombopoietin have additional independent effects. Most notable for thrombopoietin is its effect on hematopoietic stem cells illustrated by in vitro and in vivo approaches.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
