An artificial cell, synthetic cell or minimal cell is an engineered particle that mimics one or many functions of a biological cell. Often, artificial cells are biological or polymeric membranes which enclose biologically active materials. [1] As such, liposomes, polymersomes, nanoparticles, microcapsules and a number of other particles can ...
In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking a denucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell. It is used in both therapeutic and reproductive cloning.
Human cloning is the creation of a genetically identical copy of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins. The possibilities of human cloning have raised controversies.
Blood substitute. A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood. It aims to provide an alternative to blood transfusion, which is transferring blood or blood-based products from one person into another. Thus far, there are no well-accepted oxygen ...
This was significant because it was the first ever gene-edited therapy for diabetes that approached clinics. The same companies also developed a novel treatment for type 1 diabetes to produce insulin via a small medical implant that uses millions of pancreatic cells derived from CRISPR gene-edited stem cells.

Only those cells comprising the center colony are human iPS cells. Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. The iPSC technology was pioneered by Shinya Yamanaka and Kazutoshi Takahashi in Kyoto, Japan, who together showed in 2006 ...
This article is about the medical therapy. For the cell type, see Stem cell. Stem-cell therapy uses stem cells to treat or prevent a disease or condition. [ 1 ] As of 2024 [update], 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 ...
Regenerative medicine. A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [ 1 ] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own ...
