Kinetics of reprogramming in cell fusion hybrids

The International Journal of Developmental Biology
Hyun-Woo Choi, Jeong-Tae Do


Somatic cells can obtain pluripotency by fusion with pluripotent stem cells. The resulting fusion hybrids display pluripotential characteristics, such as inactivation of tissue-specific genes, differentiation potential to all three germ layers, and a specific epigenetic state corresponding to the pluripotent cells. However, the fusion hybrid cells are not identical to the pluripotent fusion partner cells although they are similar to the pluripotent cells. Recently, we showed that fusion-induced reprogramming was not a solely unidirectional process. In this review, we address how much somatic cells "remember and lose" their original characteristics after fusion with pluripotent cells.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
