In this task, you will be given sentences in which you have to recognize the name of the body cells. A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Although there might be several correct answers, you need to write one of them.
One example: HeLa cells were first treated with 250 mug / ml Trail followed by pulse labeling of newly synthesized proteins with [ 35S ] methionine.
Solution is here: HeLa cells
Explanation: HeLa cells are the first immortal human cell line. It should be tagged.

Now, solve this:  In the fetal GK / Par rat exposed to mild hyperglycemia during gestation ( a model of IUED ) , data from our group suggest that the beta - cell deficit ( reduced by more than 50 % ) starts as early as fetal age E16 and reflects decreased beta - cell proliferation , a limitation of beta - cell neogenesis from precursors , and increased apoptosis of both beta cells and their precursors [ 86 ] .
Solution:
beta cells
