[Effect of supernatant of erythroblastic island bone marrow cultures on erythropoiesis in vitro]. | LitMetric

AI Article Synopsis

  • Joint cultivation of supernatants with bone marrow erythroblastic islands influences erythropoiesis, showing either stimulatory or inhibitory effects.
  • The impact of these supernatants varies based on the culture age, amount of erythrocyte production, and length of cultivation with the bone marrow islands.
  • Short-term supernatants (24 hours) promote initial erythroblastic island formation, while medium-term (48 hours) supernatants stimulate erythropoiesis and maturation, whereas long-term (72 hours) supernatants inhibit initial formation but enhance maturation processes.

Article Abstract

It was shown that joint cultivation of supernatants with bone marrow erythroblastic islands in liquid culture systems resulted in stimulatory or inhibitory effects on erythropoiesis. Influence of supernatants on erythropoiesis depended on the culture age, erythrocyte production in these cultures and duration of joint cultivation with bone marrow islands. Supernatants of 24 h cultures induced formation of erythroblastic islands de repeto and de novo in cultures. Supernatants of 48 h cultures caused stimulation of erythropoiesis (to the end of 24 h period ofjoint cultivation) and processes of maturation in erythroblastic islands (at the 48th of joint cultivation). Supernatants of 72 h cultures inhibited formation of erythroblastic islands de novo and de repeto, but stimulated the processes of their maturation.
