Abstract

To investigate in vitro differentiation of canine adipose tissue-derived stromal cells (ATSCs) into neuronal cells, ATSCs from celiac adipose tissue in clinically healthy beagle dogs were treated with 100 μM dibutyryl cyclic adenosine monophosphate (dbcAMP) and 125 μM isobuthylmethylxanthine (IBMX). ATSCs were morphologically changed into differentiated ATSCs from spindle-shaped cells to neuron-like cells with numerous processes after the treatment. Expression of neuron-specific enolase (NSE) as an early neuron specific marker protein was detected in both ATSCs and differentiated ATSCs, however diachronic increase of NSE expression was observed in differentiated ATSCs after the treatment with dbcAMP/IBMX. In addition, neurofilament-68 (NF-68) as an early to mature neuron specific marker protein was weakly expressed in differentiated ATSCs. Neuron specific glutamate and glucose transporter (EAAC1 and GLUT-3, respectively) mRNAs were strongly expressed in differentiated ATSCs compared with those in ATSCs, although glia specific glutamate transporter mRNA (GLT-1) was also detected in differentiated ATSCs. ATSCs can differentiate into early to mature neuronal cells and are candidate cells for autologous nerve regeneration therapy, although additional research is needed to examine functional characteristics of differentiated ATSCs.
