The compliance of the tissue-engineered bladders (the quality of yielding to fluid pressure) showed almost no difference from pre-operative values. In their analysis, the investigators found that the retrieved tissue engineered bladder...... only in the heart, of a gene called CREB , which controls the activity of several other genes that regulate the growth and development of cardiac muscle.
