What is primary tissue culture? Several different types of culture are routinely performed. The Classification of tissue cultures is based on the origin of the cells; which can roughly be divided into "primary culture" and "culture of established cell lines." Primary tissue culture can consist of the culture of a complex organ or tissue slice‚ a defined mixture of cells‚ or highly purified cells isolated directly from the organism. Compared to a cell line using primary culture has the advantages

These include sebaceous glands of the skin and glands in the intestinal lining (exocrine glands)‚ and many of the endocrine glands releasing hormones‚ such as the thyroid follicle.

1. Should the Silicone-X project be undertaken? Why/why not? After completing the analysis and reviewing the NPVs and IRRs for each option‚ labor intensive and capital intensive‚ Soderberg should recommend that the Jacobs division move forward with production of Silicon-X using the labor-intensive option. The NPV and IRR methods make the same decisions if used for independent projects however‚ since these projects are mutually exclusive‚ the best NPV option should be used. In this

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE

epithelial tissues which are flat and have more than one layer. The Skin for a barrier. Your skin‚ for example‚ is a formidable barrier against many things. Skin is created when the basal cells in skin are dividing by the process of mitosis and‚ as division takes place‚ the cells get pushed upwards. As a result‚ the newer cells tend to stay near the bottom of the epithelial tissue‚ and the older cells get pushed upward and eventually are lost as they flake off. Cells flake
