(14) There are also interesting reports of adrenal medullary transplant or purified adrenal chromaffin cells' transplant for the managemant of chronic pain, (15) and pain of central origin after spinal cord hemisection, (16) and in cases of intractable cancer pain.
Carcinoid tumors are tumors composed of chromaffin tissue.
Thus, the chromaffin cell plasticity is analogous to neuronal degeneration of hippocampal neurons and apoptosis of lymphocytes.
Pheochromocytomas are rare, but potentially lethal, catecholamine-secreting tumors that arise from the chromaffin cells of the adrenal medulla and sympathetic ganglia.
Furthermore, two other reasons should be taken into account while considering genetic testing: (1) the high rate of metastatic PHEO associated with some mutations, which may aid in tailoring the appropriate follow-up [25], and (2) the finding of a mutation in the index case and their relatives, which allows for an individualized surveillance program to timely detect and treat chromaffin and other nonchromaffin cell tumors or disorders [26].
Our observation of an increased number of calcium transients upon ryanodine treatment is in accordance with previous observations in rat chromaffin cells [61].
This idea is supported by the evidence that (1) under excess and prolonged HPA axis activation, the expression of the inhibitory SOCS protein induced by gp130 cytokine (via JAK/STAT pathway) activation can, in turn, inhibit further corticotroph (via JAK/STAT) signaling and that (2) the application of IL-6 in nanomolar concentration range in adrenal chromaffin cells [85] (comparable to those observed during sepsis [49]) can activate ERK 1/2 and STAT3 pathways and lead to increased expression of target genes such as secreted neuropeptides including galanin, PTHrP, G-protein-coupled receptor (GPR), stanniocalcin-1 (STC1) and hypoxia-inducible factor 1[alpha] (HIF-1[alpha]) (Figure 2).

Researches on bovine adrenal chromaffin cells showed the influence of cotinine on the activity of C protein and the calcium concentration in these cells [20].
The cells of the adrenal medulla are composed of irregular epithelioid cells arranged in rounded groups or short cords and are mostly columnar or polyhedral chromaffin cells which are separated by sinusoids (Fig.
Different cells are immobilized to fulfill the requirement like adrenal chromaffin cells, parathyroid cells and insulin-producing cells (Langerhans islets) for the treatment of Type I diabetes (Then et al., 2012).
Paragangliomas are rare neuroendocrine tumours that arise from extra-adrenal paraganglia and consist of specialized catecholamine-secreting chromaffin cells.
