Stem cells: What they are and what they do
A stem cell line is a group of cells that all descend from a single original stem cell and are grown in a lab. Cells in a stem cell line keep growing but don’t differentiate into specialized cells. Ideally, they remain free of genetic defects and continue to create more stem …

What is a stem cell?
A stem cell is a cell with the unique ability to develop into specialised cell types in the body. In the future they may be used to replace cells and tissues that have been damaged or lost due to disease.

What are Stem Cells? Types of Stem Cell and their Uses

Stem cells are unspecialized.Unlike a red blood cell, which carries oxygen through the blood stream, or a muscle cell that works with other cells to produce movement, a stem cell does not have any specialized physiological properties. Stem cells can divide and

Stem cells: a brief history and outlook
Stem cells have been the object of much excitement and controversy amongst both scientists and the general population. Surprisingly, though, not everybody understands the basic properties of stem cells, let alone the fact that there is more than one type of cell that falls within the “stem cell” category. Here, I’ll lay out the basic concepts of stem cell biology as a background for

Stem Cell Analysis & Characterization
Stem cell research requires cellular and molecular tools to confirm pluripotency or to help determine the utility of cells in downstream experiments. Whether analyzing proliferation, protein levels, gene expression, or epigenetic profiles, we have the right instruments, products, and services for …

What are the differences between Stem Cells and …

 · Any cell type in a multicellular organism, except germline cells, is called a somatic cell. In contrast, stem cells are unspecialized cells with self-renewal capacity that can divide limitlessly to produce new stem cells, as well can differentiate to different cell types in

What is a Stem Cell Line & Its Purpose in Genetic Research?

 · A stem cell line is essentially a group of stem cells that is cultured for various purposes using in-vitro methods. Stem cell lines are commonly used in genetic research and regenerative medicine, and they have already led to countless breakthroughs that would not …

Stem Cell Ethics – The Student Scientist

 · Stem cell research is ethical because it is helpful to the society. With successful stem cell usage, it is possible to cure disease, fix organs, and identify birth defects. There would be a greater good to the country well-being if stem cells were used to help cure

Stem Cell Therapy in Retinal Disease
 · Stem cells, currently under investigation for the treatment of age-related macular degeneration and other retinal disorders, are characterized by the ability to differentiate into multiple cell lineages, and an unlimited self-renewal capacity. These traits make them

The History of the Cell: A Brief Explanation
 · The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. This content is accurate and true to the best of the author’s knowledge and is not meant to substitute for formal and individualized advice from a qualified professional.

Biology and relevance of human acute myeloid …

This cancer stem cell model offers an explanation for chemotherapy resistance and disease relapse and implies that approaches to treatment must eradicate LSCs for cure. More recently, a number of studies have both refined and expanded our understanding of LSCs and intrapatient heterogeneity in AML using improved xenotransplant models, genome-scale analyses, and experimental manipulation …

Erythropoiesis
Erythropoiesis (from Greek ‘erythro’ meaning “red” and ‘poiesis’ meaning “to make”) is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. It is stimulated by decreased O 2 in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin.

Stem cells
 · Stem cells are cells that have not undergone differentiation. A cell which has not yet become specialised is called undifferentiated. An embryo develops from a fertilised egg. All of the cells in

What is Stem Cell Research? (with pictures)

Ethical Issues Stem cell research can assist couples who have faced fertility issues. The overall debate over the ethics of stem cell research involve two major ethical concerns: (1) the potential for human cloning, and (2) whether these embryos, or pre-embryos as some refer to them, are human life.. Perhaps the initial controversy is related to the possibility of human
