Compensatory growth (organ) kidneys. Along with the kidneys, compensatory growth has also been characterized in a number of other tissues and organs including: A large number of growth factors and hormones are involved with compensatory growth, but the exact mechanism is not fully understood and probably varies between different organs. Nevertheless, angiogenic growth factors which control the growth of blood vessels are particularly important because blood flow significantly determines the maximum growth of an organ. Compensatory growth may also refer to the accelerated growth following a period of slowed growth, particularly as a result of nutrient deprivation. Compensatory growth (organ) Compensatory growth is
Subfornical organ columns and body of the fornix. Afferent fibers from the body and columns of the fornix polysynaptically excite both superficial and deep neurons. A recurrent inhibitory circuit is suggested on the output path. The expression of various genes in the subfornical organ have been studied. For example, it was seen that water deprivation in rats led to an upregulation of the mRNA that codes for angiotensin II receptors, allowing for a lower angiotensin concentration in the blood that produce the "thirst" response. It also has been observed to be a site of thyroid transcription factor 1 (TTF1) production, a protein
