Although the absolute level of tumor marker did not correlate with prognosis, a normal value indicated an improved survival. CEA was elevated in 35.2 % of 110 patients determined to have recurrent disease and CA 19-9 was elevated in 62.9 %. At least one of the tumor markers was elevated in 68.2 % of patients.
Cell Membrane In BOTH types of cells. Controls what goes in and out of the cell. Chloroplast In a PLANT CELL. Captures energy from sunlight. Uses energy to produce cell food, which is sugar. Process called photosynthesis. Cytoplasm In BOTH types of cells. Houses gel-like fluids that support cell organelles. Endoplasmic Reticulum In BOTH types of cells.
In cell division, the cell that is dividing is called the parent cell. The parent cell divides into two daughter cells. The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins.
