What is the difference between an undifferentiated cell and a differentiated cell

Some of this type of differentiated cells are epithelial cells, skin fibroblasts, endothelial cells lining the blood vessels, and smooth muscle cells. Nevertheless, some differentiated cells such as liver cells and neurons in the brain rarely undergo proliferation. In contrast, some stem cells such as cardiac muscle cells do not undergo proliferation at all. Undifferentiated cells are a type of immature cells found in the body of multicellular organisms.

They are also known as stem cells. The two main characteristic features of undifferentiated cells are their ability to self-renew while differentiating into specialized cells. Therefore, the main function of undifferentiated cells is to replenish old, injured or dead cells from the body. Additionally, these cells can be isolated and used in therapeutic and research purposes. Figure 2: Function of a Hematopoietic Stem Cell. Furthermore, there are three main types of undifferentiated cells known as embryonic stem cells, fetal stem cells , and adult stem cells.

Here, the totipotent cells of the embryo give rise to the cells of the inner cell mass identified as embryonic stem cells which are pluripotent. Further, these cells give rise to the cells in the three germ layers.

Also, fetal stem cells are the primitive cell types in the fetus. Moreover, these cells differentiate into the cells in different organs and tissues. Nevertheless, the organs and tissues of adults contain stem cells known as adult stem cells. These cells can be either multipotent such as the bone marrow cells, giving rise to several types of blood cells or unipotent, giving rise to a single type of differentiated cells.

Tissues are communities of cells that have functions beyond what any single cell type could accomplish. Healthy tissues require the proper mix of cells, and the cells within them must be oriented correctly and dividing at an appropriate rate.

In order to coordinate their function, organization, and rates of death and division, the cells in a tissue are constantly processing and responding to signals from one another and from the ECM around them.

Learn about the general structure of a eukaryotic gene, the transcription factors, and post-transcriptional regulation Genes are the blueprint of our bodies, a blueprint that creates a variety of proteins essential to any organism's survival.

Find out in this lesson the various factors that affect growth. This study guide tackles plant roots in greater detail. It delves into the development of plant roots, the root structure, and the major regions of a plant root. It also talks about the different forms of roots that have specialized functions.

Humans are capable of only one mode of reproduction, i. Haploid sex cells gametes are produced so that at fertilization a diploid zygote forms.

This tutorial is an in-depth study guide regarding male and female reproductive physiology Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid.

Find out in this guide the importance of each hormone in the life of a plant
