Resumo: | PURPOSE. Limbal epithelial stem cells (LSCs), located in the basal layer of the corneal epithelium in the corneal limbus, are vital for maintaining the corneal epithelium. LSCs have a high capacity of self-renewal with increased potential for error-free proliferation and poor differentiation. To date, limited research has focused on unveiling the composition of the limbal stem cell niche, and, more important, on the role the specific stem cell niche may have in LSC differentiation and function. Our work investigates the composition of the extracellular matrix in the LSC niche and how it regulates LSC differentiation and function. METHODS. Hyaluronan (HA) is naturally synthesized by hyaluronan synthases (HASs), and vertebrates have the following three types: HAS1, HAS2, and HAS3. Wild-type and HAS and TSG-6 knockout mice-HAS1(-/-) |

Limbal epithelial stem cells (LSCs), located in the basal layer of the corneal epithelium in the corneal limbus, are vital for maintaining the corneal epithelium. LSCs have a high capacity of self-renewal with increased potential for error-free proliferation and poor differentiation. To date, limited research has focused on unveiling the composition of the limbal stem cell niche, and, more important, on the role the specific stem cell niche may have in LSC differentiation and function. Our work investigates the composition of the extracellular matrix in the LSC niche and how it regulates LSC differentiation and function. METHODS. Hyaluronan (HA) is naturally synthesized by hyaluronan synthases (HASs), and vertebrates have the following three types: HAS1, HAS2, and HAS3. Wild-type and HAS and TSG-6 knockout mice-HAS1(-/-)HAS3(-/-), HAS2(Delta/Delta CorEpi), TSG-6(-/-) -were used to determine the importance of the HA niche in LSC differentiation and specification. RESULTS. Our data demonstrate that the LSC niche is composed of a HA rich extracellular matrix. HAS1(-/-)HAS3(-/-), HAS2(Delta/Delta CorEpi), and TSG-6(-/-) mice have delayed wound healing and increased inflammation after injury. Interestingly, upon insult the HAS knock-out mice upregulate HA throughout the cornea through a compensatory mechanism, and in turn this alters LSC and epithelial cell specification. CONCLUSIONS. The LSC niche is composed of a specialized HA matrix that differs from that present in the rest of the corneal epithelium, and the disruption of this specific HA matrix within the LSC niche leads to compromised corneal epithelial regeneration. Finally, our findings suggest that HA has a major role in maintaining the LSC phenotype.Univ Fed São Paulo, São Paulo, BrazilUniv Houston, Coll Optometry, 4901 Calhoun Rd, Houston, TX 77204 USASanford Burnham Med Res Inst, Sanford Childrens Hlth Res Ctr, La Jolla, CA USAChang Gung Univ, Chang Gung Mem Hosp, Dept Ophthalmol, Coll Med, Linkou, TaiwanCleveland Clin, Cleveland, OH 44106 USAUniv Fed São Paulo, São Paulo, BrazilWeb of ScienceUniversity of HoustonMizutani FoundationNational Institutes of Health (NIH)/National Eye InstituteNIH: P30 EY07551Assoc Research Vision Ophthalmology Inc2019-08-19T11:48:38Z2019-08-19T11:48:38Z2017info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion4407-4421application/pdfhttp://dx.doi.org/10.1167/iovs.17-22326Investigative Ophthalmology & Visual Science.
