What I found interesting about the nucleus and did not know, is that is had a double nuclear envelope. I also found it interesting that the outer envelope is continuous with the endoplasmic reticulum
I find it difficult to understand how the proteins being transported out of the cell know where to go, and how to get there?!
Apoptosis is a cellular process which requires lots of energy from mitochondria (produces ATP ie energy).
N-CAM: Neural cell adhesion molecule.
Ng-CAM: Neuron glia cell adhesion molecule.
L-CAM: A neuronal cell adhesion molecule of the L1 protein family?
I-CAM: Inter-cellular adhesion molecule
Stratum spinosum is the layer between the basal and granulosa layer. The cells of the stratum spinosum synthesize intermediate filaments. The filaments help support and resist abrasion of the skin.
I found that the phenotype of the control B35 cells differed markedly from the Tm4 over-expressing B35 cells in that the control there were overall many more cells. There were nearly 4 times as many stumped cells in the wild type, and about 2 times as many prolonged and stringed. Also, there were no observed pygnotic cells in the Tm4 ever-expressing B35, however there were a few in the wild type. The over-expression of Tm4 may have led to the inhibition of cell formation, or of cells undergoing mitosis (division). This leads to the observed decrease in overall cell numbers.
