Stem cells used to generate mini brains of the last male Sumatran rhino

Researchers generated induced pluripotent stem cells (iPSCs) and cerebral organoids from the last male Malaysian Sumatran rhino, according to a study published in the journal iScience on October 20. As noted by the authors, the organoids could contribute to knowledge about the evolutionary progression of brain development in mammals and may help to unravel the ancient history of the rhinoceros family.
