Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

This paper reports important findings on giant organelle complexes containing endosomes and lysosomes (termed endosomal-lysosomal organelles form assembly structures [ELYSAs]) present in mouse oocytes ...

Here, we demonstrate that the molecular chaperone heat shock protein A2 (HSPA2), a member of the 70 kDa heat shock protein (HSP70) family, is asymmetrically expressed in the late 2-cell stage of mouse ...

FIGURE 7. The main role of m 6 A in the stage of embryonic development. The level of m6A modification increased slowly in mouse 2-cell, 4-cell and 8-cell embryos but suddenly increased significantly ...

Researchers found that the concentration of menthol in the blood of pregnant women who vape is enough to activate ...

For some animals, the entire process of cellular multiplication, generation of specialized cells, and their organization into an ordered multicellular embryo takes place in the protective environment ...

First Mouse With Two Male Parents to Reach Adulthood Jan. 28, 2025 — A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a ...

Researchers have performed the first known transplant of sperm-producing stem cells in hopes of restoring fertility in a man ...

Scientists at a technology company said Sunday they have created human embryos through cloning, drawing criticism from President Bush and lawmakers and raising new ethical questions. Advanced Cell ...

After three washes in 0.2 M sodium cacodylate and 1.6% NaCl buffer ... Stage E1.0 (Stage 1, day 1 of development). The zygote (1-cell embryo) consists of a single fertilized cell. The stage extends ...

Officials at ARM, ASGCT, and ISCT convened a small group of scientists, policy experts, religious leaders and patient ...

Pluripotent stem cells are cells that have the capacity to self-renew by dividing and to develop into the three primary germ cell layers of the early embryo and therefore into all cells of the ...
