retinal cells from second-trimester fetuses can be expanded into a large number of undifferentiated cells in vitro and mature retinal cells [14]. These cells can be ideal sources for transplantation when considering a dose-response relationship in pre-clinical and clinical studies. We previously reported on the technical feasibility

have identified a combination of four transcription factors that can directly reprogram the human retinal pigment epithelium (RPE) cell line ARPE19 into RGC-like cells. Expression of ATOH7, BRN2, BRN3B, and MYT1 in ARPE19 cells transformed their morphology to a neuronal phenotype and induced the expression of pan-neuronal and RGC-associated genes.

Moreover, abnormal tracking or localization of rhodopsin leads to dys-function and death of photoreceptors cells [12, 13]. As previously described [14], we accomplished a tar-

How are organisms organized? Many-celled organisms are organized in cells, tissues, organs, and organ systems. Cells: Animals and plants are many-celled organisms. Animals are made up of many kinds of cells. You are made of blood cells, bone cells, skin cells, and many others. A plant also has different cells in its roots, stems, and leaves.

coordinate the activities of all of the other white blood cells and are essential for fighting disease. There are two major types of T cells: Helper T cells (T H) and Killer T cells (T K). Helper T cells send signals that activate the rest of your immune system to fight a germ. Killer T cells patrol the body and eliminate infected cells.

Cells in multicellular organisms are specialized for a specific function. In animals, skin cells provide protec-tion, nerve cells carry signals, and muscle cells produce movement. Cells of the same type are organized into a group of cells that work together. For example, what you think of as muscle is muscle tissue, made up of many muscle cells.

Plant cells have all the same phases as animal cells. However, there is one important structure that plant cells have that animal cells do not which makes "cell pinching" impossible. It is the cell wall. In plant cell division, a "cell plate" forms between the new cells. The cell plate grows into the cell wall between the new cells. Slide 26 / 168
