Collenchyma cell have thicker primary walls than parenchyma cell‚ though the walls are unevenly thickened. Young stems and petioles often have strands of collenchyma cells just below their epidermis. Collenchyma cells lack secondary walls‚ and the hardening agent lignin is absent in their primary walls. Therefore‚ they provide flexible support without restraining growth. At functional maturity‚ collenchyma cells are living and flexible‚ elongating with the stems and leaves they support. Grouped in

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

There are thousands of burn victims awaiting donations of human tissue to help meet critical needs in reconstructive surgery. My current case #49 regards the selling of human tissue donations. It’s a complicated situation where a few medical centers have acquired a partnership with a biotechnological company called Ardias Corporation. Ardias wants to create a tissue bank to help facilitate researchers with disease-specific tissue that will provide a link to accurate genetic sequence with diseases

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
