Culture of blood cells, mainly erythrocytes, at industrial levels complying with cGMP regulations, aim to make them available, at large scale, any time and everywhere, when needed for transfusion, or laboratory applications. Understanding how blood cells differentiate and develop in-vivo, and mechanisms of differentiation and growth factors, has opened newer strategies for in-vitro culture from multipotent stem cells or immortalized lines. This offers interesting perspectives for obtaining such cultured bioproduct cells for medical applications. In addition, many attempts for preparing platelets in-vitro from megakaryocyte culture have been reported. Nevertheless, the quantities of functional viable platelets obtained are still not sufficient to envisage transfusion applications. Other strategic approaches concern culture of organoids, which can synthesize functional blood proteins, but still significant scale-up of yield needs to be addressed. Finally, considerable advances have been made in culturing specific lymphocytes for personalized immunotherapy of some cancer patients with highly promising results in certain applications. This concise mini report focuses on the progress made in these directions, and attempts are made to describe some newer perspectives.
