Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...

Stem Cell Therapy for Tissue Regeneration

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Stem Cell Culture

Stem Cell Culture

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

Source And Potency Of Stem Cells

Source And Potency Of Stem Cells

Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Tissue Renewal without Stem Cells

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Area of Science:

Regenerative Medicine
Thoracic Surgery
Stem Cell Biology

Background:

Bronchial stump dehiscence is a severe complication following lung resection, associated with high mortality rates (25-75%).
Effective strategies to enhance bronchial stump healing are crucial for improving surgical outcomes.

Purpose of the Study:

To investigate the histologic effects of adult stem cells on bronchial stump healing after lung resection.
To evaluate the potential of bone marrow-derived stem cells in reducing post-operative complications.

Main Methods:

A left pneumonectomy was performed on 36 Wistar rats.
Half of the rats received topical application of labeled bone marrow-derived stem cells to the bronchial stump.
Rats were sacrificed on days 7 and 21 for macroscopic and histopathologic analysis.

Main Results:

Stem cell treatment led to significantly fewer adhesions on days 7 and 21 (P = .042 and .031).
Complete bronchial stump healing (restitutio ad integrum) was observed more frequently in the stem cell group by day 21 (P = .012).
Reduced inflammation in all layers of the bronchial stump was noted in the stem cell group at day 21 (P < .050).

Conclusions:

Topical bone marrow-derived stem cells migrate to the bronchial wall and actively participate in healing.
Stem cell administration results in decreased adhesions and inflammation.
This regenerative approach promotes enhanced tissue regeneration of the bronchial stump.
