Scientists Grow Whole Model of Embryo Without Sperm or Egg

Scientists have grown a whole model of embryo without sperm or egg, in a breakthrough that could help us understand human development and could one day lead to new ways to treat infertility.

The research, published in the journal Nature, was conducted by a team of scientists from the University of California, San Francisco (UCSF).

The team used a technique called induced pluripotent stem cells (iPSCs) to create a model of a human embryo.

iPSCs are cells that have been reprogrammed to act like embryonic stem cells. This means that they can be used to create any type of cell in the body.

The UCSF team used iPSCs to create a model of a human embryo at the blastocyst stage, which is about five days after fertilization.

The blastocyst is a ball of cells that contains the cells that will eventually become the embryo’s tissues and organs.

The team then placed the blastocyst-like structure in a dish and watched it develop over time. They found that the structure grew and differentiated into different cell types, just like a real embryo.

This is the first time that scientists have been able to grow a whole model of an embryo without sperm or egg. The research could help us understand how human development works and could one day lead to new ways to treat infertility.

The study’s senior author, Dr. Hiromitsu Nakauchi, said that the research could “open up new possibilities for studying human development and for developing new treatments for infertility.”

Dr. Nakauchi said that the team is now working to improve the model so that it can be used to study more aspects of human development.

He said that the team is also working to develop ways to use the model to create new treatments for infertility.

The research is a significant advance in the field of stem cell research and could have a major impact on our understanding of human development.

It could also lead to new ways to treat infertility and other diseases.
