Enhancing the immunosuppressive capacity of human-umbilical-cord–derived mesenchymal stem cells

The immunosuppressive capacity of mesenchymal stem cells (MSCs) is dependent on the "license" of several proinflammatory factors to express immunosuppressive factors such as programmed cell death 1 ligand 1 (PD-L1), which ...

Constitutive aryl hydrocarbon receptor facilitates regenerative potential of mouse bone marrow mesenchymal stromal cells

Bone marrow mesenchymal stromal cells (BMSCs) are the commonly used seed cells in tissue engineering. Aryl hydrocarbon receptor (AhR) is a transcription factor involved in various cellular processes. However, the function ...

Quercetin ameliorates oxidative stress-induced senescence in rat nucleus pulposus-derived mesenchymal stem cells: Study

Intervertebral disk degeneration (IDD) is a main contributor to low back pain. Oxidative stress, which is highly associated with the progression of IDD, increases senescence of nucleus pulposus-derived mesenchymal stem cells ...

Discovery of how stem cell niche guides differentiation into functional cells is a significant step towards therapies

Researchers at the Hong Kong University of Science and Technology (HKUST) have found how stem cells' surrounding environment controls them to differentiate into functional cells, a breakthrough critical for using stem cells ...

Researchers discover how stem cells choose their identity

AMOLF researchers discovered that stem cells first specialize into a functional cell and then move to their proper location—rather than the other way around.

Scientists find way to wipe a cell's memory to better reprogram it as a stem cell

In a study published in Nature, Australian scientists have resolved a long-standing problem in regenerative medicine. Led by Professor Ryan Lister from the Harry Perkins Institute of Medical Research and The University of ...

Researchers reveal role of protein oxidative folding in stem cell aging

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 ...

Generation of a human haploid neural stem cell line for genome-wide genetic screening

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 ...

Commitment of human mesenchymal stromal cells to skeletal lineages is independent of their morphogenetic capacity: Study

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 enhances cell adhesion, migration, self-renewal potential of human umbilical cord-derived mesenchymal stem cells

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 ...
