Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.
Culture medium
DMEM (High Glucose) + 10% FBS
Cryopreservation medium
Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Notes

Recommended control: Human wild-type HeLa cell line (ab255448). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.

We will provide viable cells that proliferate on revival.

Activity summary

Hairless also known as HR is a nuclear receptor corepressor that plays an important role in hair follicle development. With a molecular mass of approximately 130 kDa it acts mechanistically by interacting with transcription factors to regulate gene expression. Hairless is expressed mainly in the skin particularly in the hair follicles but it can also be found in other tissues like the brain adipose tissue and testes. Its ability to localize in the nucleus allows Hairless to directly control chromatin structure and transcriptional activity.

Biological function summary

Hairless is involved in the regulation of hair cycling and differentiation. It functions as part of a larger repressor complex recruiting histone deacetylases to histones which results in gene silencing. This activity is important for the transition between different phases of the hair growth cycle such as anagen and telogen phases. Hairless also plays a role in repressing certain genes involved in epidermal differentiation thereby maintaining stem cell populations necessary for continuous hair growth.

Pathways

Hairless significantly impacts the Wnt signaling pathway and the Notch signaling pathway. In the Wnt pathway Hairless collaborates with proteins like beta-catenin to influence follicle morphogenesis and hair cycle progression. In the Notch signaling cascade Hairless interacts with Notch receptors regulating cell fate decisions during hair development. These pathways are essential for proper hair follicle regeneration and maintenance highlighting Hairless's critical role in hair biology.

Associated diseases and disorders

Hairless has been implicated in alopecia universalis a condition characterized by complete hair loss. Mutations in the Hairless gene can result in faulty protein function causing disruption in hair development and cycling. Furthermore Hairless has ties to Marie Unna hereditary hypotrichosis a genetic disorder leading to sparse hair and scalp abnormalities. The implicated pathways also involve proteins such as Notch1 and beta-catenin which are associated with defects in hair follicle development and structure.
