It has been widely acknowledged for a long time that mitochondrion is the main source of reactive oxygen species (ROS). The role of the endoplasmic reticulum (ER)-generated ROS has been less extensively studied. It has been ...
Haploid embryonic stem cells (haESCs) have been established in many species. Differentiated haploid cell line types in mammals are lacking due to spontaneous diploidization during differentiation that compromises lineage-specific ...
Mesenchymal stromal cells (MSCs) are multipotent cell populations obtained from fetal and adult tissues. They share some characteristics with limb bud mesodermal cells such as differentiation potential into osteogenic, chondrogenic, ...
Zinc (Zn) is the second most abundant trace element after Fe, present in the human body. It is frequently reported in association with cell growth and proliferation, and its deficiency is considered to be a major disease ...
Regenerative medicine has opened up exciting possibilities in the world of medicine. Now, researchers in Japan are searching for ways to recreate and rebuild body tissues and organs, which may be an alternative cure for diseases.
As a human embryo grows, a set of molecules directs cells as they multiply and take on specific identities and spatial positions within the embryo. In one crucial step known as gastrulation, these signaling molecules guide ...
Induced pluripotent stem (iPS) cells have a great impact on biology and medicine, and they are expected to improve regenerative medicine. Since 2014, when a sheet of retinal pigment epithelial cells derived from iPS cells ...
How do cells become cancerous, multiply uncontrollably, and form into tumors? And what role do aberrant embryonic stem cells play? These are big questions explored by medical researchers since the embryonic theory of cancer ...
Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth and why many pregnancies fail.
In humans, pregnancy lasts around nine months. In mice, only 20 days, and in rhinoceroses, as long as 17 months. Although many mammalian species go through the same stages during embryo development, the speed of development ...
