In this section we describe and display the latest results from our conducted R&D on industrial and medical applications  concerning our PATENTS OF DENOVO BIOENGINEERED HAIRFOLLICLE. 

06. MARCH 2019 Experimental Description [ hematoxylin eosin staining]

→HAIROIDs (date of fixation 30. JUNE 2018) were immersed in 4%PFA (5 Eppis-008) and stored at 4°C until procedure start 

• Samples: 008-23; 008-24; 008-32; 008-16; 008-47

→HAROIDs were embedded in cryomatrix

• From the first HAIROID (008-23), BF were taken to recognize the morphology of the HAIROID and to check hair follicle-like structures

→Consecutive 6 µm sections were recollected from the entire HAIROID.

HAIROID ™️ 8-23.: Entire overview 

HAIROID™️ 8-24. SLIDE 17.2: Consecutive sections are showing a new forming HF (red arrow). HS is shown in light-brown. Structure stained in red (blue arrow) are showing many HS-like structures inside. Green arrows are showing crossectioned HFs.

HAIROID ™️ 8-32. SLIDE 12.3: Overview of the entire HAROID. Red arrows are showing  a hair follicle-like structure where it is possible to observe a clear dermal papila. Blue arrows show crossections of HAIRFOLLICLES.

HAIROID ™️ 8-32.: Consecutive sections showing 2 different HFs. It is possible to observe in both HFs the dermal papila, hair matrix, outer and inner root sheath. 

06. April 2019 Historical Experimental set up Autumn 2017 of our PATENT 

Our project leader wrote in his report:

„In vivo vs. in vitro:
Stemness markers NESTIN, SOX-2, p63 are present in vivo and in vitro
In agreement with the literature these stem cells are Keratin 14 and 15 negative
Expression needs to be further verified via gene expression analysis
Assay design for optimization of stemness promoting conditions ongoing
Next Step extraction of cells of higher potency (LHX2/SOX9+)

General remarks:
Stable in vitro cultures of potential DP or better HFSC over at least 12 passages
Stability of proliferation rate will be further assessed, but can be considered as stable
Cryopreservation of HFSC is working efficiently
Reprograming from this population will be tested Q1 2018
Non-invasive extraction from hair will be tested Q1 2018“
HAIROID™️ PT 1 . 18.10.2017:  Day 0, Media combination 1.Hair Bulge Stem Cell (HBSC) derivation from Dermal papilla in vitro.

HAIROID™️ PT 2 . 30.10.2017:  Day 10, Media combination 3. Dermal papilla expansion in vitro.

HAIROID™️ PT 1 . 04.01.2018:  Media combination 1. Spontaneous HF formation?.... “TBC”  

19. September  2019  Experimental bio- printing set up Autumn 2019 with our autologous protocol.

Our project leader wrote in his report:

[ ...] attached document are images of the 2d expansion, the printing process and the constructs one day post printing – when the fibroblasts and follicle cells are in the constructs. The follicle cells can be seen forming aggregates within the pores created with the bioprinted dermal construct....the keratinocytes were added to the constructs today and are left for attachment overnight.

Important notice:

Currently there’s no GMP compliant medical tissue bio printing technology available - all recently developed-  bio printed hairfollicles, or hair inducing stem cell approaches, are laboratory grade experiments and can’t be used in patients.

The printed hairfollicle tissues at HAIROID ™️ are used for  R&D of FUROID ™️ biomaterials or for the production of HAIROID ™️ human hairfollicle tissues for cosmetic and medical compound testing purposes. For more details on biomaterials please visit

HAIROID™️ FUROID™️ Printing Project 1 . 17.09.2019 NON GMP COMPLIANT: 

Image of construct 1 day post bioprinting, prior to addition of keratinocytes. Bioprinted grid structure is clearly visible with follicle dermal papilla cell aggregates formed within the pore structures. Scattered dots are the fibroblasts within the dermal matrix. 4x magnification.

HAIROID™️ FUROID™️ Printing Project 1 . 17.12.2019 NON GMP COMPLIANT:

Image of construct 33 day post bioprinting.  Bioprinted grid structure is clearly visible with hair-follicle aggregates formed within the pore structures. The hair-follicles are inseparably attached. This model serves as an in vitro test system for cosmetics and medical applications furthermore as biomaterial for various industrial applications.
