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.

Example Input:  ( D ) Confocal images of C - terminally FLAG - tagged MOR1K overexpressed in Be2C cells and stained with either Anti - FLAG M2 Antibody Alexa Fluor Conjugate or fluorescent - labeled naloxone ( FNAL ) .
Example Output: Be2C cells

Example Input:  Dextransucrase ( EC 2 . 4 . 1 . 5 ) , which catalyses soluble glucan synthesis , was most active in the supernatant fluid from cultures grown with excess glucose , fructose or sucrose , but full activity was detected only when the enzyme was incubated with both sucrose and dextran .
Example Output: EC

Example Input:  Be2C cells transfected with either MOR1 or MOR1K isoforms showed increased retention of FNAL at concentrations of 0 . 1 and 1 muM .
Example Output:
Be2C cells
