Microengineered Gradient Hydrogels for Mechanobiology

open access: yesAdvanced Healthcare Materials, EarlyView.
Gradient hydrogels are used to mimic the mechanical heterogeneity in native tissues, offering powerful in vitro platforms to study cell‐material interactions in diverse pathophysiological contexts. Here, we present a comprehensive review of the design and experimental considerations for stiffness gradient hydrogels, discussing exemplary achievements ...

Early cell fate decisions of human embryonic stem cells and mouse epiblast stem cells are controlled by the same signalling pathways.

open access: yesPLoS ONE, 2009
Human embryonic stem cells have unique value for regenerative medicine, as they are capable of differentiating into a broad variety of cell types. Therefore, defining the signalling pathways that control early cell fate decisions of pluripotent stem ...

Human Pluripotent Stem Cells for Corneal Applications : Therapeutic potential of human pluripotent stem cell-derived corneal limbal stem cells

open access: yes, 2022
Sarveiskalvo on silmän etuosaa suojaava läpinäkyvä kudos, jolla on keskeinen rooli näkökyvyn mahdollistamisessa. Sen uloin osa koostuu kerrostuneesta, jatkuvassa uusiutumissyklissä olevasta epiteelisolukosta. Tätä jatkuvaa uusiutumista ylläpitävät limbaalisiksi kantasoluiksi (engl.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

open access: yesAdvanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for

Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

Challenges and possible clinical applications of human embryonic stem cell research [PDF]

open access: yes, 2012
Human embryonic stem cells (hESC) are harvested from the inner cell mass of the pre-implantation embryo and possess several unique characteristics. First, they are self-renewing, meaning they can grow indefinitely in an appropriate culture environment ...

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

Comprehensive insight into chicken germline cells: A review

open access: yesPoultry Science
Genetic information is propagated in the progeny through germ cells. The stem cells which are precursors of these germ cells have the ability of self-renewal and can give rise to pluripotent stem cells under favorable conditions.

Generation of stem cell-derived β-cells from patients with type 1 diabetes

open access: yesNature Communications, 2016
Pancreatic β cells can be generated from pluripotent stem cells. Here, the authors show that human induced pluripotent stem cells from patients with type 1 diabetes can be differentiated into β-like cells that have no detectable differences compared with
