Queste microsfere (chiamate microcarrier) sono progettate per trasportare cellule sane ai tessuti danneggiati per aiutarli a ripararsi. Normalmente, questi prodotti che trasportano cellule devono essere prodotti freschi, il che ne rende difficile la produzione e la distribuzione. I ricercatori hanno testato diversi metodi di congelamento e scongelamento e hanno scoperto che le cellule muscolari sono sopravvissute bene, sono rimaste attaccate alle sfere e si sono comportate normalmente anche dopo lo scongelamento. Anche le perle stesse sono rimaste strutturalmente sane. Ci\u00f2 significa che in futuro questi trattamenti a base di cellule potrebbero essere prodotti in anticipo, conservati in una \u201ccatena del freddo\u201d e consegnati agli ospedali quando necessario, rendendo le terapie rigenerative molto pi\u00f9 pratiche e accessibili.<\/p>\n<p><em>Astratto<\/em><\/p>\n<p>Obiettivi di fondo: Le terapie di medicina rigenerativa includono costrutti di ingegneria tissutale per ripristinare la funzione di tessuti e organi.

Cytotherapy 12th September 2025. Summary This study looked at whether tiny, implantable beads carrying human muscle cells can be safely frozen and stored for later medical use. These beads (called microcarriers) are designed to deliver healthy cells to damaged tissues to help them repair themselves. Normally, these cell-carrying products must be made fresh, which makes them difficult to manufacture and distribute. The researchers tested different freezing and thawing methods and found that the muscle cells survived well, stayed attached to the beads, and still behaved normally after thawing. The beads themselves also remained structurally sound. This means that in the future, these cell-based treatments could be produced in advance, stored in a \u201ccold chain\u201d and delivered to hospitals when needed, making regenerative therapies much more practical and accessible. Abstract Background aims: Regenerative medicine therapies include tissue-engineered constructs to restore tissue and organ function. Among the different approaches, implantable polymeric microcarriers have been proposed for delivery of anchorage-dependent cells to target tissue locations. Cell-microcarrier combinations produced as fresh advanced therapy medicinal products face significant challenges in terms of manufacturing and time distribution.

Current therapeutic usage of SMDC relies on harvesting autologous cells from muscle biopsies that are subsequently expanded in vitro before re-implantation into the patient. Heterogeneity can arise from multiple factors including quality of the starting biopsy, age and comorbidity affecting the processed SMDC. Quality attributes intended for clinical use often focus on minimum levels of myogenic cell marker expression. Such approaches do not evaluate the likelihood of SMDC to differentiate and form myofibres when implanted in vivo, which ultimately determines the likelihood of muscle regeneration. Predicting the therapeutic potency of SMDC in vitro prior to implantation is key to developing successful therapeutics in regenerative medicine and reducing implementation costs. Here, we report on the development of a novel SMDC profiling tool to examine populations of cells in vitro derived from different donors. We developed an image-based pipeline to quantify morphological features and extracted cell shape descriptors. We investigated whether these could predict heterogeneity in the formation of myotubes and correlate with the myogenic fusion index. Several of the early cell shape characteristics were found to negatively correlate with the fusion index. These included total area occupied by cells, area shape, bounding box area, compactness, equivalent diameter, minimum ferret diameter, minor axis length and perimeter of SMDC at 24 h after initiating culture. The information extracted with our approach indicates live cell imaging can detect a range of cell phenotypes based on cell-shape alone and preserving cell integrity could be used to predict propensity to form myotubes in vitro and functional tissue in vivo.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Access the full paper here:&nbsp;<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/36949843\/\">https:\/\/pubmed.ncbi.nlm.nih.gov\/36949843\/<\/a><\/p>\n<!-- \/wp:paragraph -->","_et_gb_content_width":"","_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","_links_to":"","_links_to_target":""},"categories":[43],"class_list":["post-31516","publication","type-publication","status-publish","has-post-thumbnail","hentry","category-publication"],"_links":{"self":[{"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/publication\/31516","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/publication"}],"about":[{"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/types\/publication"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/media\/31519"}],"wp:attachment":[{"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/media?parent=31516"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/amelie-project.eu\/it\/wp-json\/wp\/v2\/categories?post=31516"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
