Which of the following is/are expected challenges in the field of tissue engineering?     Creating artificial scaffolds that provide the correct signals to direct cell behavior.     Finding the correct combination of chemical and mechanical signals to direct cells to undergo morphogenesis and/or differentiation when grown on a scaffold.     Obtaining stem cells that are capable of attaching to a scaffold and responding appropriately to it to assemble a functional organ.     a, b, and c

Fill in the following boxes:

How do simple tissues differ from complex tissues? Give examples.

Tissue engineering combines living cells with synthetic materials to create functional substitutes for human tissues. What components would you use to engineer a replacement for facial skin? Include an adequately labeled sketch/diagram.

Tissues, Organs, & Systems Multi-cellular organisms have many cells that work together in specific ways, each group performing certain functions. When each group does its part, the organism gets everything that it needs. A Tissue is a large group of cells that all have the same purpose or function. Each kind of cell has unique characteristics such as shape, size, flexibility, color and texture. Nerve cell combined with other nerve cell to make nerve tissue. Muscle cell combined with other muscle cell to make muscle tissue. Bone cell combine with other bone cell to make bone tissue. An Organ is a group of tissues that work together to do a certain job for the body. Some of the human body’s organs include the stomach, lungs, heart, kidneys, brainand liver. Some of a plant’s organs include roots, stems, fruit and leaves. When several different organs join to meet the organism’s needs, they are working together in an organ system. There are several different organ systems constantly…

22) the function of stem cells in this region of a tissue is to increase the number of cells that go on to differentiate into parenchymal cells  a) transmit amplifying zone b)organizer zone c) parenchymal cell zone d) all of these e) none of these

Search for an image of a microscope slide (not a diagram) of a tissue. point out the distinguishing characteristics that you use to identify the tissue. (shape of cells, number of layers, shape of groups of cells, etc.) Don't include the function of the tissues or the cells. Focus on shape and number of layers.
