Which specialized cells are created from stem cells? Check all that apply.
vampirchik [111]
<h2>Answer:</h2>

I believe the correct answer is all of the cells.

<h2>Explanation:</h2>

All cells usually arise from stem cells. Stem cells have the ability to reproduce, differentiate or specialize into specific stem cells. There are multipotent, totipotent and pluripotent types of stem cells that give rise to specific types of cells.

<h2>Further Explanation:</h2><h3>1. Red and White blood cells:</h3>

These are essential blood cells confined to blood vessels and tissues. Red blood cells (Erythrocytes) function to carry oxygen to tissues and carbondioxide away from tissues while white blood cells (leukocytes) function as defensive barries protecting the body from infections and any type of foreign/pathogenic material. They have multipotent stem cells called multipotent haematopoietic stem cells that further specialize into the common myeloid progenitor and the common lymphoid progenitor. The common myeloid progenitor differentiates into the megakaryocytes that form platelets, erythrocytes (red blood cells), mast cells and myelocytes ( white blood cells that have granules in them i.e. basophils, neutrophils, eosinophuls and monocytes). The common lymphoid progenitor forms lymphocytes which are small types of white blood cells that fight cancers and viruses. Cancers can cause stem cells of specific cells to multiply uncontrollably or suppress the production of specific cells causing adverse health issues.

<h3>2. Muscle cells:</h3>

Muscle cells grow from stem cell precursors depending on their type. There are skeletal muscles (muscles that support bones in their functions), smooth muscles( found in organs such as the lungs) and cardiac muscles (specific only to the heart). Skeletal muscle stem cells are called satellite cells, while cardiac and smooth muscles arise from the cardiac neural crest stem cell.

<h3>3. Neurons</h3>

Neurons are specialized cells for communication in the body and include neurons found in the central nervous system and the peripheral nervous system and glial cells that provide support for them. They arise from the neural stem cells to form common progenitors differentiating into neurons and glial cells.

<h3>4. Epithelial cells</h3>

They are part of the most abundant cells in the body. They populate every organ surface in the body. They arise from the epithelial stem cells forming different types of epithelial cells in regards to the surface they are found. e.g. Keratinized epithelial cells are found in openings and surfaces of the body i.e. the eyes, skin, vagina, mouth and ear canals while non-keratinized are found in internal hollow surfaces such as the lungs, spleen, liver, kidneys.
