What treatment is being compared to the control in the experiment? what treatment is being compared to the control in the experiment? the treated umbilical cord stem cells were cultured in the presence of an inhibitor from glioblastoma cells, but the control cells were cultured without the inhibitor. the control glioblastoma cells were run through the flow cytometer and then treated by being cultured in the presence of an inhibitor. the treated glioblastoma cells were stained with a fluorescent dye, but the control cells were not stained. the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor?

The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.

It has been shown that treatment with injected umbilical cord stem cells has strong therapeutic effects on glioma models. Those cells produce anti-tumour substances, with inhibitory effects.

Control group does not include the treatment in order to observe the treatment.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
