Apud Cells and Paraneurons: Embryonic Origin

摘要: Publisher Summary This chapter reviews the main aspects of concept amine precursor uptake and decarboxylation (APUD) that was aimed at grouping diverse cell types whose common feature ability to synthesize so-called biogenic or monoamines. In period development APUD concept, it noticed take up precursors such as dopa 5-HTP decarboxylate them with formation monoamines catecholamines serotonin a number types. Criteria for membership series have changed in present. extended paraneuron emphasize close relationship between conventional neurons neuron-like cells, paraneurons, some which are cells located amphibian cutaneous glands, placenta, thymus, hypothalamus sympathetic ganglia. Cells monoamine-storing avian aortic wall regarded paraneurons. The study similarities paraneurons has helped recognition fact polypeptide-secreting endocrine not completely disparate entities.
