Generally, in each stem cell division, one cell remains a stem cell, while the other goes on to differentiate the stem cells themselves usually divide rather infrequently (and are rather rare. This lecture will introduce the various types/sources of stem cells as well as their practical and therapeutic potentials a brief discussion of the pros and cons of different types of stem cells currently investigated in the field of medical research will be discussed.

The ultimate stem cell - the newly fertilized egg (one cell) will give rise to all the cells and tissues of the adult animal truly totipotential but difficult to use. T lymphocytes account for 65-80% of peripheral blood lymphocytes and are functionally divided into t helper cells (predominate in blood) and t suppressor cells (predominate in marrow) b lymphocytes : these have endogenously produced ig molecules on the cell surface , which act as receptors for specific antigens.

Cell organelles - notes cell theory cells are the basic unit of life the cell theory states that: 1) all organisms are made up of one or more cells and the products of those cells. 1 lecture notes: (cells & tissues) cells i introduction a) modern cell theory (1) all organisms are composed of at least one cell (2) all cells are similar in their chemical composition.
J cells come in a variety of shapes, & the shape helps determine the function of the cell (eg nerve cells are long to transmit messages in the body, while red blood cells are disk shaped to move through blood vessels.

Lecture notes - cell biology a) water potential ( ) it is the tendency of water molecules to move the more solute dissolved in water, the lower is its water potential since the water potential of pure water is defined as zero, the water potential of solutions always a negative value. Cell culture cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (eg, metabolic studies, aging), the effects of drugs and toxic compounds on the cells.
