• Over millions of years of evolution, mitochondria and chloroplasts have become more specialized and today they cannot live outside the cell. (utah.edu)
• Mitochondria and chloroplasts have striking similarities to bacteria cells. (utah.edu)
• In plant cells, ATP is produced in the cristae of mitochondria and chloroplasts. (enchantedlearning.com)

Somatic cell4

• Somatic-cell nuclear transfer, the technique by which Dolly was created, was first used 40 years ago in research with tadpoles and frogs. (who.int)
• The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
• if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (who.int)
• This cell then has therapeutic cloning: the global the capacity to divide and grow into an exact replica of the original from whom the debate somatic cell was taken. (who.int)

Tumor2

• Large clump of abnormal cells called tumor. (planetayurveda.com)
• Its metastatic potential depends on the phenotype of the tumor cells, and it frequently disseminates before diagnosis. (medscape.com)

Cloning5

• 5. In 2001, France and Germany requested the United Nations General Assembly to develop international conventions on human reproductive cloning, therapeutic cloning and research on stem cells. (who.int)
• When the nucleus of a stem cell has been the technique of cloning. (who.int)
• The con- is removed and replaced by a nucleus of cept of human cloning has long been in the another cell type, the stem cell will then imagination of many scientists, scholars and be reprogrammed to produce the product fiction writers [ 1 ]. (who.int)
• The basic techniques of of the implanted nucleus, when it fully cloning have been known for some time, and develops. (who.int)
• This paper outlines the debates prompted through a reproduction mechanism involv- by progress in cloning research, with special ing male and female germ cells. (who.int)

Proliferation3

• OPC architecture, proliferation and oligodendro-/myelino-genesis are finely regulated by the interplay of cell-intrinsic and extrinsic factors. (nature.com)
• Both a cell-intrinsic program and environmental factors participate in the regulation of OPC architecture, proliferation and oligodendro-/myelino-genesis. (nature.com)
• proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), and cell movement. (medlineplus.gov)

Contrast1

• In contrast, all the supporting and Schwann cells are derived from neural crest cells, possibly from the VIIth nerve ganglion to which the vestibulocochlear ganglion is initially attached. (medscape.com)

Nuclear envelope1

• The nuclear envelope is a double-membrane structure that constitutes the outermost portion of the nucleus. (coursehero.com)

Movement1

• Facilitated diffusion is a type of passive transport where a "helper" molecule assists in the movement of solute across a cell membrane. (proprofs.com)

Human7

• 12 In human cells, the diameter of the nucleus is approximately six micrometres (µm). (wikipedia.org)
• Interaction with human PPIA/CYPA protects the virus from restriction by human TRIM5-alpha and from an unknown antiviral activity in human cells. (proteopedia.org)
• The human body composed of trillions of cell. (planetayurveda.com)
• If you are trying to understand human anatomy and physiology, it all begins with understanding the cells that make up the human body. (proprofs.com)
• It is vast, yet fits within the nucleus of a single cell and challenges the human mind's concept of the finite. (twu.edu)
• The stem cells suits human needs, does not cause harm and can be obtained from both adult and fetal does not conflict with religious beliefs, it has tissues, umbilical cord and early embryos. (who.int)
• Unicellular for those cells that are derived from human organisms are primed to replicate (clone) pre-embryos, which seem to have a high themselves by nature. (who.int)

Liver1

Basal cells2

• Such period is related to the amount of time that the basal cells take to reach the surface and exfoliate. (bvsalud.org)
• Melanocytes can be found between the basal cells of the hair matrix. (medscape.com)

Replication1

• Opposite to the mitotic spindle, the separation of chromosomal replication is done through the cell membrane. (differencebetween.net)
