Every human being is different, therefore we all have different susceptibilities to suffer from a particular disease and we all react differently to certain medications. All INVITROHAIR approaches are entirely based on human induced pluripotent stem cells (iPSCs), consequently they are a priori personalized. While we usually make use of a library of available, well characterized human iPSCs, we are extending our activities to fully personalized approaches. Based on a small FUE- sample (an amount of 30 FUExcission obtained  hairfollicles) we can generate personalized hairfollicle organoids. This service is only offered to physicians after regulatory clearance. These HAIROIDS will be used for several potential applications:


Alopecia is often diagnosed at a rather late stage of the disease progression. We aim at further developing our hair  organoid technology to be able to predict disease susceptibility long before the first symptoms become observable.

Personalized - INVITRO- drug testing*

For any indication where more than one drug is available, pre-testing on our personalized INVITRO application (and on the planned use of personalized hair-on-the-chip devices) is conceivable, so that only the drug which showed maximal effect is then prioritized  for the patient.

3D human  hair organoids*

The unique feature of our approach is that we use complex 3D human  organoids whereas we’re bioengineer the organ to a level that is not achievable by traditional in vitro cell culture. Hence, by using the individual's cells we are able to generate on-a-dish a model of the organs. This allows the identification/correction of potential defects and the pre-test of drugs when multiple choices are available.

For these services, we make use of our expertise in the generation of human induced pluripotent stem cells (iPSCs). All our approaches are therefore completely free of any kind of animal testing.

The iPSCs are used to generate human hair organoids for disease modelling, drug testing and transplantation.

Furthemore our bioengineered hair organoid requires the isolation of Dermal Papillae (DPSC) - HB- stem cells, their merge with IPSC and their cryogenic storage.

At the end of our service we deliver all original data as well as a report with the analysed results. We are aware of the importance of maximal quality of data analysis, integration (e.g. via tranSMART) visualization and security (Tier4 data storage centre). To ensure this state of the art service we closely work together with our own formed biomedical IT-company.

Conclusion of INVITROHAIR precision medicine approach*

INVITROHAIR developed a clear process for its precision medicine applications. The current pipeline is as follows:

1) Medical doctors with interested patients get in touch with INVITROHAIR .

2) At a certified INVITROHAIR physician  (hair restoration surgeon ) 30 hairfollicle samples from patients are taken.

3) Samples are transported to INVITROHAIR ‘ processing facility.

4) INVITROHAIR is  performing assays, isolates DPSC and reprograms  induced pluripotent stem cells from these samples.

5) Stem cells are characterized (quality checks), expanded and banked.

6) In consultation with INVITROHAIR’ medical director  the requested modeling approaches will be performed. This is always fully specific for the affected individual (see applications above).

7) INVITROHAIR drafts a report, including recommendations and provides this report to the medical director.

8) INVITROHAIR is able to provide some certain denovo hairfollicles which are either autologous / or human leukocyte antigen protein matching ( HLAs) hypoimmunogenic   - derived from patients own/ or donated samples- other stem cells - tissues ( where the protocols are described and developed ) for TRANSPLANTATION. 

 *This services are only offered after regulatory clearance, the subsequent described procedures, in the patients section of our webpage, are meant for informational purposes solely and do not construct any promise of treatment or therapy. After the obtention of regulatory approval from competent governmental authorities INVITROHAIR  will perform procedures under strict scientific and regulatory rigor and safety measures. This service is only offered to physicians.
