Biotechnology for Medicine (continued-1)

The use of natural diversity for therapeutic purposes is not limited only to fungi and actinomycetes that produce antibiotics.

Biotechnology for medicine

The use of biotechnology of the potential of living organisms in the vital interests of man, his research and economic activities allows solving various problems.

Cloning

Stem cells

"Stem" model of carcinogenesis

The common features of stem and cancer cells allowed us to call malignant ancestral cells cancer stem cells. These cells appear to be the result of a malfunction in the regulatory system of damaged stem cells or their direct descendants.

Is there a connection between the nature of stem cell division and the neoplastic process?

A potential cost for the frequent use of symmetrical stem cell division is an increase in the frequency of cancer that occurs during the transformation of somatic stem cells.

Genetic regulation of stem cell pluripotency (continued)

Embryonic stem cells (ESCs) have a so-called minimal phenotype and a minimum of receptors and programs for interacting with the microenvironment.

Genetic regulation of stem cell pluripotency

Stem cells would not be interesting for developmental biology and clinical medicine if they did not have pluripotency and would not be able to start development again.

Genes that make stem cells

The identification of genes that determine the properties of stem cells will not only accurately identify these types of cells, but also open up new opportunities to control them during cultivation and therapeutic use.

To what extent do the characteristics of stem cells determine their therapeutic capabilities

The considerable interest that currently exists in stem cells is primarily due to the prospects for their biomedical application.

Types of stem cells and their properties

Stem cells are defined as undifferentiated cells capable of self-renewal and differentiation into specialized cells.

Stem Cells: Introduction

The practical use of stem cells will change traditional approaches in the treatment of many diseases and give people the main thing - health, youth, longevity.

Genetic engineering

Genetic engineering is an integral part of modern biotechnology, its theoretical basis is molecular biology, genetics.

Genetics

What secrets of longevity do studies on model objects tell about (continued-2)

The role of Sirtuin family genes as potential longevity genes extends to mammals as well.

What secrets of longevity do studies on model objects tell about (continued)

Studies on model objects have revealed a whole family of genes that affect the lifespan of various organisms.

What secrets of longevity do studies on model objects tell about

To date, significant progress in the study of aging genetics has been achieved thanks to work on various model objects.

The genetic component of life expectancy

Genetic regulation of individual development (ontogenesis) is associated with the sequential implementation of various genetic programs in time, ending with the death of an individual.

Viruses have regulated humans

A complex system of regulation of the body at the DNA level, a person may be obliged to retroviruses – distant relatives of HIV. It seems that they gave the "emperor gene" of primates, which controls gene expression in monkeys and humans, its current status.
