A multidisciplinary team of researchers has succeeded in developing different types of organoids from cells obtained from amniotic fluid. According to the authors, this breakthrough could help to better understand the later stages of development during pregnancy and to advance research into congenital anomalies. The study is published in the journal Nature Medicine.
Scientists have successfully developed pig embryos whose kidneys contain 50-60% human cells. Gestation was terminated at 25-28 days, and the organ structure was normal. According to the press release accompanying the article, "this is the first time that a solid humanised organ has been grown inside another species, although previous studies have used similar methods to generate human tissues". The results are published in the journal Cell Stem Cell.
A US team has successfully integrated brain-like tissue derived from human stem cells into the brains of newborn rats. The research is published in the journal Nature.
