What Are The Types Of Stem Cells – You may have heard about stem cells in science blogs, newspaper articles, and even on social media! You should also be aware of claims that stem cells are “miracle cells,” “life-giving,” and even can cure cancer. Yes, you heard right. Stem cells can do all this, but how do they work? Well, it all comes from different sources of stem cells. The characteristics of stem cells usually vary depending on the source from which they are derived. So, are you ready to learn about stem cells, their classifications and uses? Let’s start with the definition of stem cells!

The term stem cells was first introduced by William Sedgwick in 1886 to describe the “regenerative quality” of plants.

What Are The Types Of Stem Cells

They are defined as multipotent cells that differentiate into muscle cells, red blood cells, brain cells, cardiac muscle cells, and bone cells. 2

What Is Stem Cell?

Stem cells can be divided into 2 broad categories based on the source of the stem cells and their differentiation potential.

Stem cells from human embryos are available 4-7 days after fertilization. Of course, these cells are pluripotent (have the ability to transform into different cells and tissues). Embryonic cells are obtained by in vitro fertilization for ethical reasons.

In addition to being pluripotent, these cells have other unique properties such as self-renewal, structural repair and growth, and rapid cell division. Clinical applications of embryonic stem cells (iPSCs/ developed from adult cells) have shown therapeutic potential and are being considered in the management of diabetes and cardiovascular disease.

Scientists have discovered a way to reprogram mature human cells to mimic the traits of embryonic stem cells in the form of induced pluripotent stem cells (iPSCs).

Stem Cell Therapy

These stem cells are taken from the fetus and can be removed from the embryo after 8 weeks. Fetal stem cells can be obtained from fetal blood, bone marrow, or other fetal tissues such as liver and kidney. 10

Compared to adult stem cells, fetal stem cells are better internalized, pluripotent, and less immunogenic.

Adult stem cells (ASCs) are pluripotent cells that can regenerate damaged or dead tissue. They can be found in some of the body’s dividing tissues.

The main function of ASCs in our body is to constantly repair, regenerate and replace cells that need to be replenished. Only 3 types of cells can develop from adult stem cells—nerve cells, mesenchymal cells, and hematopoietic stem cells.

Types Of Mesenchymal Stem Cells (mscs) And Their Mechanisms Of Action

These stem cells are taken from the umbilical cord blood (and placenta) of the newborn. 14 Umbilical cord blood contains hematopoietic stem cells used in the treatment of many genetic diseases, cancers, and hereditary diseases.

So far, we have discussed the categories based on the different sources of stem cells. Now, let’s see how stem cells are categorized based on their differentiation potential.

Totipotent stem cells have the ability to differentiate into any cell. The zygote formed during fertilization is one of the best examples of this because it can develop into any cell type, including the placenta. 3 The only totipotent stem cells in the human body are those produced by embryonic stem cells after the first two cell divisions.

Embryonic stem cells are considered pluripotent because they can differentiate into any cell type other than placental cells. In addition, pluripotent cells are produced during the early stages of embryonic stem cell differentiation. However, they can also be derived from germ layers (groups of cells during embryonic development).

Mesenchymal Stem Cells Definition, Origin And Clinical Applications

Multipotent stem cells are present in almost all tissues. MSCs or Mesenchymal cells are a common example of multipotent stem cells. These stem cells can be obtained from adipose tissue, bone marrow, peripheral blood, and even umbilical cord blood.

After learning about the different types of stem cells, you may be interested in their uses. Here we have listed a few uses of stem cells (some of which are still in the early research stage):

Did you know? Advances in modern medicine have allowed new parents to save stem cells from their baby’s umbilical cord blood? Yes, you heard us right. This advance is called stem cell banking, and it offers protection and care (against potential diseases and disorders) for the newborn as well as the entire family (including siblings, biological parents, mother and grandparents). .

If you want to know some interesting facts about umbilical cord blood stem cells and the diseases they can cure, check out our “read more” section. Happy reading! Stem cells are unspecialized cells with unique abilities to self-renew and differentiate into other cell types. They represent powerful tools for the study and investigation of disease mechanisms and have great potential for use as cell-based therapies.

Stem cells can be broadly divided into two categories: pluripotent cells and adult stem cells. Pluripotent stem cells consist of embryonic stem cells (ES) derived from the inner cell mass of the blastocyst (an early stage of the mammalian embryo that forms approximately five days after fertilization) and induced pluripotent stem cells (iPSCs). is generated by reprogramming mature cells to an ES cell-like state through the expression of pluripotency-regulating genes.

A defining characteristic of pluripotent stem cells is their ability to form almost any cell type (ES cells cannot form cells of the placenta). This is in contrast to adult stem cells, which are found in tissues or organs and are instead multipotent, meaning they are limited to differentiating into the cell types of the tissue or organ in which they reside. ES cells give rise to mature mammalian organisms, and adult stem cells serve to replace cells lost through natural aging, disease, or injury.

Examples of adult stem cells include endothelial cells, which form the endothelium (the inner lining of blood vessels and lymph vessels); hematopoietic stem cells that form blood cells; mesenchymal stem cells that differentiate into cell types such as osteoblasts, adipocytes, myocytes, and hepatocytes; and become nerve cells, astrocytes, oligodendrocytes, and other cell types associated with the nervous system.

What Is A Stem Cell?

In addition to the cells mentioned above, it is known that there are other types of stem cells. Totipotent stem cells have the ability to give rise to any type of cell, including placental cells, and occur during the first few cell divisions of embryonic development. Cancer cells are found within tumors and are thought to play a central role in relapse and metastasis, making them potential therapeutic targets to prevent disease recurrence. Plant stem cells also have stem cells that share some similarities in function with mammalian stem cells.

Stem cells are widely useful for scientific research and are widely used in growing organoids, 3D multicellular organisms.

Enabling tissue constructs to model development and disease and test experimental drug treatments. Importantly, the use of stem cells for research reduces the need for animal testing while providing physiologically relevant data. For example, stem cell based

Systems have been proposed to better predict toxic risks in humans compared to using established animal models because they eliminate the problem of interspecies variability.

What Is Stem Cell Research?

Stem cells also hold great promise as cell-based therapies and have already been successfully used in bone marrow transplants, corneal transplants, and skin transplants. Conditions for which stem cell therapy is currently being developed include rheumatoid arthritis, muscular dystrophy, Crohn’s disease, multiple sclerosis, Alzheimer’s disease, and cancer.

A major challenge when working with stem cells is maintaining the purity and properties of cell populations. Stem cells must be obtained from a reliable supplier and cultured under strictly controlled conditions to ensure that differentiation occurs correctly and only when necessary. It is recommended to use a growth medium optimized for the cell type in question, and it is important that any cytokines or growth factors are sterile and low endotoxin, as well as proven biological activity.

Cellular characterization presents further challenges. Stem cells and their differentiated progeny are identified using techniques such as flow cytometry and immunocytochemistry to detect markers, including cell surface proteins, transcription factors, and intracellular signaling molecules. However, since many cell types show overlapping marker expression, precise detection usually involves simultaneous detection of multiple targets. High-quality antibody reagents are essential to avoid misidentifications that can lead to costly delays.

Another challenge for stem cell research arises from the fact that human and mouse stem cells have different mechanisms for regulating pluripotency and differentiation. Understanding these differences is key when it comes to reagent selection and protocol optimization.
