Lab-cultured mouse embryos, grown for an extended period, offer a new window on fetal development In the course of an experiment pushing the length limits of in vitro growth, mouse embryos went from translucent clumps of cells to fetuses with beating hearts and blood cells. Image credit: Jacob Hanna In a potential methods breakthrough, stem cell biologists grew mouse embryos for five-and-a-half days in vitro, longer than ever before. Appearing recently in Nature, the study unveils new protocol...

Jun Wus team at the University of Texas Southwestern Medical Center in Dallas have created hollow balls of cells that closely resemble embryos at the stage when they usually implant in the womb — known as blastocysts. The new laboratory-made embryo-like entities have been dubbed "blastoids."

Scientists have created a model of an early human embryo from skin cells, a discovery which they say will revolutionise research into the causes of early miscarriage, infertility and early human development. Researchers have successfully reprogrammed these fibroblasts or skin cells into a 3D cellular structure that is similar to human blastocysts. Called iBlastoids, these can be used to model the biology of early human embryos in the laboratory, according to a new study. Scientists say this is ...

The new laboratory-made embryos have been dubbed "blastoids." These structures made from living human cells are similar to human embryos at the stage when they implant in the womb. They allow scientists to research new ways to treat inf...

Researchers have successfully grown model versions of early human embryos by “reprogramming” cells from human skin. The breakthrough potentially opens up new ways to study the earliest phases of human development, learn more about developmental disorders, infertility and genetic diseases, and perhaps even improve the success of IVF treatment. In a study published in Nature today, a team led by our colleague Jose Polo discovered that when skin cells are treated in a particular way, 3D struc...

Share This lab-grown ball of human cells shares many similarities with 5-day-old human embryos. UNIVERSITY OF TEXAS SOUTHWESTERN MEDICAL CENTER Researchers re-create key human embryo stage in lab Mar. 17, 2021 , 12:25 PM A human embryo at the blastocyst stage is smaller than the tip of a ballpoint pen and may contain fewer than 100 cells, but this developmental waypoint has long puzzled and vexed biologists and physicians. Many miscarriages occur during this stage, for example, and a bl...

For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of restrictions on using real embryos.

Updated 3/17/2021 12:03 PM WASHINGTON -- For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of restrictions on using real embryos. Two papers published Wednesday in the journal Nature detail how two teams of scientists independently made such structures.   They stressed that their work is only for research, not reproduction, but it likely will pose new et...
