When cultured in three dimensional (3D) assays the D 492 cell line forms branching structures with an inner layer of luminal epithelial cells and an outer layer of myoepithelial cells clearly showing a bipotential phenotype, correct histoarchitecture and thus stem cell properties.
Frumur D 492 mynda greinótta formgerð í þrívíðum ræktunum með innra lag af kirtilþekjufrumum og ytra lag af vöðvaþekjufrumum sem styður undir stofnfrumueiginleika frumulínunnar.
