Descrizione del progetto
Modelli in vitro di malattie neuromuscolari
I modelli di tessuto 3D in vitro o organoidi imitano l’architettura e il microambiente dei tessuti o degli organi viventi e hanno suscitato interesse in diversi campi di ricerca, tra cui la biologia, la farmacologia e la modellazione delle malattie. Finanziato dal Consiglio europeo della ricerca, il progetto MusclePlate intende sviluppare in vitro analoghi 3D del muscolo scheletrico per modellare i disturbi neuromuscolari (NMD). La piattaforma comprenderà un design unico e un sistema di stimolazione luminosa per il controllo optogenetico della contrazione muscolare. Saggi basati su immagini e algoritmi computazionali forniranno informazioni sulla struttura e sulla funzione muscolare. MusclePlate dovrebbe rivoluzionare lo screening dei farmaci per gli NMD, portando potenzialmente a nuove terapie per i pazienti affetti da NMD.
Obiettivo
Neuromuscular disorders (NMDs) are a collection of pathologies that affect the skeletal muscle (SkM) function and lead to reduced mobility, breathing issues and death. Most NMDs are incurable and existing therapies are generally ineffective. The major contributor for the lack of NMD therapies is the absence of human NMD research models, applicable for the screening and validation of therapeutic candidates. Our goal for this project is to develop an in vitro platform containing highly biomimetic and functional SkM analogues, where NMDs can be modelled with the aim of testing drug candidates, in a reliable, high-throughput (HT), and quick manner. The platform will consist of 96 individual 3D tissue units, generated from the myogenic differentiation of human induced pluripotent stem cells (hiPSCs). To induce biomimetic and mature tissue formation, the platform will combine a unique topographical design with a light-stimulation system for optogenetic control of SkM contraction. Using image-based assays and computational algorithms, we will be able to automatically extract and quantify the SkM phenotypical (e.g. intracellular structure) and functional (e.g. contraction speed/force) parameters. To show NMD modelling ability within the platform, we will knockout BIN1, a gene whose mutated form is involved in the onset of centronuclear myopathy (CNM), a fatal and incurable NMD. The validity of the NMD model as a drug discovery platform will be demonstrated by testing compounds with known therapeutic activity. This proof of concept project will lay the ground work for a spin-off company devoted to HT drug screening for NMDs.
The successful development of this platform will provide an invaluable tool for pharmaceutical research, allowing accurate, convenient and cost-effective identification of novel drugs and therapeutic targets for NMDs and, ultimately contributing to the acceleration of novel therapies for NMD patients.
