Con este método se puede mirar el hueso casi tal cual está en el cuerpo, algo clave para entender fracturas, osteoporosis y cómo responden los huesos a tratamientos. Para quien tenga un familiar con osteoporosis, esto significa que los diagnósticos y las terapias futuras podrían basarse en observaciones más fieles a la realidad. Pero el método se probó solo en huesos de ratón, y falta ver si funciona igual en tejido humano.","quienFirma":"bioRxiv (preprint sin revisión por pares; institución de los autores no identificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"c8859ccfaa12402817b5d5305d25a6e3460ab7045dbb1f11f381028ef2c534a1","sello":"32e6457dc3455c64a787f3959ae47beb8653d410fd3a133bac10dd254d400fe3","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575955,"aleatorio":"883abc21527507a1c3290aa8c639d7e3e92e3d640b8aef4eeb34433d60f0e169","tiempo":"2026-10-22T22:54:30.000Z"},"nist":null,"noAntes":"2026-10-22T22:54:30.000Z"},"verificacion":{"drand":true,"nist":null},"tsa":{"time":"Oct 22 22:55:01 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Microscale Characterization of Undecalcified Bone Tissue Using Correlative Atomic Force Microscopy and Histology","descripcion":"Characterizing bone tissue in its mineralized state remains technically challenging. Conventional approaches typically compromise mechanical integrity through decalcification or lack the structural resolution necessary to capture microscale heterogeneity. Here we present an integrated workflow combining atomic force microscopy (AFM) with histological and immunofluorescence assays on adjacent undecalcified bone tissue cryosections. Using a tape-transfer mounting approach, we resolve mechanically and structurally distinct tissue types within a minimally processed single mouse femur section. Furthermore, we show that decalcification substantially alters nanoscale surface topography and local me","pubDate":"2026-10-22","url":"https://www.biorxiv.org/content/10.64898/2026.10.16.759704v1?rss=1"},"indexado":"2026-10-22T22:54:28.111Z"}}
