There are five types of stem cells, and MSC's are multi-potent, meaning they are cells that have the ability to develop into more than one type of specialized cell. Mesenchymal stem cells were originally discovered and studied as fibroblast-colony-forming cells in guinea-pig bone marrow and spleen cells by Friedenstein in the 1970s. [8]
The hip implant for dogs is similar to its human counterpart, but it is much smaller. X-rays are used to determine the dimensions of an appropriately sized implant. [3] The femoral stem is usually made of cobalt chrome or stainless steel, while the cup is made of ultra high molecular weight polyethylene.
Stem-cell therapy uses stem cells to treat or prevent a disease or condition. [1] As of 2024, the only FDA-approved therapy using stem cells is hematopoietic stem cell transplantation. [2] [3] This usually takes the form of a bone marrow or peripheral blood stem cell transplantation, but the cells can also be derived from umbilical cord blood.
It covers contemporary and emerging areas in stem cells, including embryonic and adult stem cells, and related lineage and cloning issues. The journal also publishes reviews covering basic, clinical, biotechnology, regulatory, and ethical aspects of stem cell research and applications. [1] The journal got its current name in 2009 from Stem Cell ...
Autologous stem-cell transplantation is distinguished from allogenic stem cell transplantation where the donor and the recipient of the stem cells are different people. [2] It can be also used as an Assisted reproductive technology to improve the reproductive outcomes. In a first step the bone marrow derived stem cells are mobilized.

Preparing a cow for udder surgery in field conditions: the physical restraint with a set of ropes is necessary next to xylazine tranquilisation A cat spay. Veterinary surgery is surgery performed on non-human animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics (bones, joints, muscles), soft tissue surgery (skin, body cavities, cardiovascular system ...
Induced pluripotent stem cells are similar to natural pluripotent stem cells, such as embryonic stem cells, in many aspects, such as the expression of certain stem cell genes and proteins, chromatin methylation patterns, doubling time, embryoid body formation, teratoma formation, viable chimera formation, and potency and differentiability, but ...
