Establishment of Human Pluripotent Stem Cell‐Derived Skin Organoids Enabled Pathophysiological Model of SARS‐CoV‐2 Infection
Open accessAbstract
Coronavirus disease 2019 (COVID-19) patients with impact on skin and hair loss are reported. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is detected in the skin of some patients; however, the detailed pathological features of skin tissues from patients infected with SARS-CoV-2 at a molecular level are limited. Especially, the ability of SARS-CoV-2 to infect skin cells and impact their function is not well understood. A proteome map of COVID-19 skin is established here and the susceptibility of human-induced pluripotent stem cell (hiPSC)-derived skin organoids with hair follicles and nervous system is investigated, to SARS-CoV-2 infection. It is shown that KRT17+ hair follicles can be infected by SARS-CoV-2 and are associated with the impaired development of hair follicles and epidermis. Different types of nervous system cells are also found to be infected, which can lead to neuron death. Findings from the present work provide evidence for the association between COVID-19 and hair loss. hiPSC-derived skin organoids are also presented as an experimental model which can be used to investigate the susceptibility of skin cells to SARS-CoV-2 infection and can help identify various pathological mechanisms and drug screening strategies.

PSOs are already being adopted for various applications including disease modeling and regenerative therapy.
“Despite their recent discovery, PSOs are already being adopted for various applications including disease modeling and regenerative therapy [5,7–9], yet several considerations remain, such as their limited maturation and efficiency, and non-anatomical organization of dermal and epidermal compartments.”
From Efficient Generation of Skin Organoids from Pluripotent Cells via Defined Extracellular Matrix Cues and Morphogen Gradients in a Spindle‐Shaped Microfluidic Device (2024) · cites this paper as [9]
The Introduction (page not provided) says the authors used a skin organoid to model SARS-CoV-2 infection, supporting disease modeling. The Discussion (page not provided) proposes treating complex skin disease with organoids as a possible future application; it does not show that PSOs are already being adopted for regenerative therapy.

Experimental — accuracy not yet measuredhiPSC-derived skin organoids have hair follicles, pigmentation, dermal stratification, appendage patterning, and innervation.
“Recent advances in human induced pluripotent stem cell (hiPSC) technology have enabled the generation of skin organoids (SKO) with hair follicles, pigmentation, dermal stratification, appendage patterning, and innervation.[ 25 , 26 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]”
From Coordinated Development of Immune Cell Populations in Vascularized Skin Organoids from Human Induced Pluripotent Stem Cells (2025) · cites this paper as [30]
The Results (‘Formation of Skin Organoids with Various hiPSC-Derived Skin Cells’; page unavailable) report mature hair follicles and a stratified epithelium. The Results (‘SARS-CoV-2 Can Infect the Nervous System of Skin’; page unavailable) also show a neuronal network around the follicles. But the paper identifies melanosome-related proteins rather than demonstrating visible pigmentation, and it does not establish dermal stratification or appendage patterning; epithelial stratification is not dermal stratification. (LLM, conf=0.87)
Experimental — accuracy not yet measuredPrevious human SKO models were devoid of vascularization and immune cells.
“Previous human SKO models were devoid of vascularization and immune cells.[ 25 , 26 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 59 ]”
From Coordinated Development of Immune Cell Populations in Vascularized Skin Organoids from Human Induced Pluripotent Stem Cells (2025) · cites this paper as [30]
The Results section describes this skin organoid’s cell types and reports proteins associated with vascular-related cells, but does not establish whether it has vascularization. Neither the supplied passages nor searches for vascularization and immune cells establish that this model—or previous human skin organoid models—lacked both features.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
