چکیده
|
Telocytes (tcs) are a novel type of interstitial cell of whom presence has been recently documented in many tissues and organs. however,whether tcs exists in bone marrow is still not reported. this study aims to find out tcs in mice bone marrow by using scanning electron microscope (sem) and transmission electron microscope (tem). sem images showed that in mice bone marrow most of tcs have small spherical cell body (usually 4-6 μm diameter) with thin long telopodes (tps; usually one to three). the longest tp observed was about 70 μm,with an uneven calibre. direct intercellular contacts exist between tcs. tem shows mitochondria within dilations of tps. also,by tem,we show the close spatial relations of tps with blood vessels. in conclusion,this study provides ultrastructural evidence regarding the existence of tcs in mice bone marrow,in situ. © 2014 the authors. journal of cellular and molecular medicine published by john wiley & sons ltd and foundation for cellular and molecular medicine.
