Establishment of dermal sheath cell line from Cashmere goat and characterizing cytokeratin 13 as its novel biomarker

Biotechnol Lett. 2018 May;40(5):765-772. doi: 10.1007/s10529-018-2532-5. Epub 2018 Mar 31.


Objective: To establish a dermal sheath cell line, a dermal papilla cell line and a outer root sheath cell line from Cashmere goat and clarify the similarities and differences among them.

Results: We established a dermal sheath cell line, a dermal papilla cell line and a outer root sheath cell line from the pelage skin hair follicles of Cashmere goat. The growth rate of dermal sheath cells was intermediate between that of dermal papilla cells and outer root sheath cells. Immunofluorescence experiments and reverse transcription-polymerase chain reaction analysis showed that at both the transcriptional and translational levels, the dermal sheath cells were alpha-smooth muscle actin (α-SMA)+/cytokeratin 13+, while the dermal papilla cells were α-SMA+/cytokeratin 13- and the outer root sheath cells were α-SMA-/cytokeratin 13+. Patterns of cytokeratin 13 expression could distinguish the dermal sheath cells from the dermal papilla cells.

Conclusions: These results suggest that cytokeratin 13 could serve as a novel biomarker for dermal sheath cells of Cashmere goat, and should prove useful for researchers investigating dermal stem cells or interaction of different types of cells during hair cycle.
