A Brief Overview of Stem Cells

Stem cells are primitive, undifferentiated cells that can potentially turn into a wide variety of cell types. Liver cells, blood cells, and muscle cells are only a few of the specialized types that have their origin in stem cells. Aside from their ability to differentiate into cells with specific functions, they can also divide or renew themselves indefinitely.

 

 

Because they can repair and regenerate damaged tissue, stem cells continue to command the attention of biomedical researchers who seek insights into the prevention and treatment of various diseases. In the 21st century, researchers have made several breakthroughs that have broadened our understanding of stem cells, which are expected to grow in importance over the coming years as an essential laboratory research tool.

 

Types of Stem Cells

Not all stem cells have the same degree of differentiation ability. For that reason, they are commonly categorized according to the types of cells they can differentiate into. These categories run as follows:

 

5 types of stem cells

 

Note: From Cade Hildreth, “Do you know the 5 types of stem cells?”

(https://bioinformant.com/do-you-know-the-5-types-of-stem-cells-by-differentiation-potential/)

 

  • Totipotent – Capable of turning into any type of cell.

  • Pluripotent – Capable of turning into a cell from the three primary cell layers (mesoderm, endoderm, and ectoderm).

  • Oligopotent – Capable of turning into several cell types.

  • Multipotent – Capable of turning into a closely related type of cell.

  • Unipotent – Capable of turning into only one type of cell.

 

Origins of Stem Cells

Stem cells can be classified into three distinct groups, according to their origin:

 

  • Embryonic stem cells

    – These are pluripotent cells that derive from embryos in the blastocyst stage (1-2 weeks after fertilization).

  • Adult stem cells

    – They are present in small quantities within, and can be derived from, most tissues found in adults. Generally, unipotent or multipotent, they cannot differentiate into as many types of cells as embryonic types.

    However, it was discovered in 2006 that adult stem cells can be altered in a laboratory to behave very similarly to embryonic stem cells—that is, with the ability to change into many types of cells. These modified adult stem cells are known as induced pluripotent stem cells (iPSCs).

    Mesenchymal stem cells (MSCs) are another type of adult stem cell that are derived from the stroma of the bone marrow.

  • Cancer stem cells

    – Derived from tumors and hematological cancers (e.g., chronic lymphocytic leukemia), they have the characteristics of normal stem cells, including the ability to renew themselves. Discovered in the late 1990s, they hold special promise for cancer researchers.

 

Uses of Stem Cells

Although the full potential of stem cells has yet to be realized, they already play a major role in the research and treatment of various diseases and conditions. Present-day applications of stem cells include the following:

 

  • ●Disease research – Researchers increasingly rely on stem cells for insights into diabetes, arthritis, heart disease, Alzheimer’s disease, Parkinson’s disease, and many other disorders of the body in addition to various cancers.
  • ●Genetic research – Stem cells are useful here as a means of pinpointing genetic defects.
  • ●Drug research – Stem cells can also be used to test the safety and efficacy of new drugs.
  • ●Bone marrow transplants – This procedure involves the use of hematopoietic (blood) stem cells to replace diseased or damaged bone marrow.

Cancer associated fibroblasts: how do they contribute to cancer progression?

Image
Cancer associated fibroblasts (CAFs), or Carcinoma associated fibroblasts, can contribute to cancer progression through multiple mechanisms, including the secretion of soluble factors and extracellular matrix, physical interactions with cancer cells, the regulation of  angiogenesis , immunity and metabolism, and resistance to chemoprevention according to many present researches. Therefore, CAFs are attracting increasing attention as a therapeutic target in cancer. What is CAF s ? Tumors are multicellular tissues consisting of not only tumor cells but also resident cells in the local stroma. Fibroblasts are a significant portion to the cell composition of most solid tumors, including prostate cancer, lung cancer, breast cancer, gastric cancer, colorectal cancer, and pancreatic cancer. CAF cells, which mainly originate from local tissue fibroblasts, are a heterogeneous population of activated fibroblasts found within the tumor microenviron...

Application of MDA-MB-series Cell Lines in Breast Cancer Research

Image
The Relationship between Breast Cancer and Breast Cancer Cells Breast cancer  is the leading cause of cancer death among women in developed countries[1]. The majority of breast cancer patients are over 50 years old. However, the result of new cases study shows that the number of breast cancer patients under 45 years old has exceeded 10%[2].   Currently, most of the breast cancer knowledge comes from in vivo and in vitro studies using  breast cancer cell lines  because they can provide unlimited amounts of homologous self-replicating material using simple but standard media[3]. Therefore, it is essential to know whether these cell lines can capture molecules well before obtaining any clinically relevant results.   Breast Cancer MDA-MB-series Cell Lines Establishment MDA-MB- series tumor cell lines were established from M. D. Anderson Hospital and Tumor Institute. They have created a total of 19 MDA-MB series of cell lines from female patients ...

Bone Cancer and Bone Cancer Cell Lines

Bone and Bone Cancer Bone The bone is a rigid organ that protects other organs and supports the body[1, 2]. There are about 300 bones in a newborn baby, and some of them will fuse during growth and development, and finally, 206 pieces are left in adulthood[3]. The main structures of bones include the outer cortex composed of dense bone[4], internal cortical bone[5], marrow[6], and cells[5]. Bones have a variety of functions, including a variety of mechanical functions[7], the Synthetic function of bone marrow ( hematopoiesis )[8], and are involved in body metabolism (such as mineral and fat storage,  pH balance regulation , detoxication, and calcium balance regulation). Besides, some diseases or injuries also occur in the bones, such as fractures, tumors, osteoporosis, etc.[9].     Figure.1  Microstructure of bone tissue   Tumor and  B one Cancer Bone has the possibility of tumorigenesis, which may affect the bones to a certain extent. Benign tumors are mos...
