Although it has a relatively good regeneration capacity, it cannot heal in the case of disease or severe damage. Many current tissue engineering strategies fall short due to the complex structure of skeletal muscle. Biofabrication techniques have emerged as a popular set of methods for increasing the complexity of tissue-like constructs. In this paper, 4D biofabrication technique is introduced for fabrication of the skeletal muscle microtissues. To this end, a bilayer scaffold consisting of a layer of anisotropic methacrylated alginate fibers (AA-MA) and aligned polycaprolactone (PCL) fibers were fabricated using electrospinning and later induced to self-fold to encapsulate myoblasts. Bilayer mats undergo shape-transformation in an aqueous buffer, a process that depends on their overall thickness, the thickness of each layer and the geometry of the mat. Proper selection of these parameters allowed fabrication of scroll-like tubes encapsulating myoblasts. The myoblasts were shown to align along the axis of the anisotropic PCL fibers and further differentiated into aligned myotubes that contracted under electrical stimulation. Overall the significance of this approach is in the fabrication of hollow tubular constructs that can be further developed for the formation of a vascularized and functional muscle.<\/jats:p>","DOI":"10.1088\/1758-5090\/ab4cc4","type":"journal-article","created":{"date-parts":[[2019,10,10]],"date-time":"2019-10-10T22:45:12Z","timestamp":1570747512000},"page":"015016","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":68,"title":["4D biofabrication of skeletal muscle microtissues"],"prefix":"10.1088","volume":"12","author":[{"given":"Indra","family":"Apsite","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Manuel","family":"Uribe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0032-2224","authenticated-orcid":false,"given":"Andr\u00e9s Fernando","family":"Posada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabine","family":"Rosenfeldt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6740-4195","authenticated-orcid":false,"given":"Sahar","family":"Salehi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0770-6140","authenticated-orcid":false,"given":"Leonid","family":"Ionov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2019,12,11]]},"reference":[{"key":"bfab4cc4bib1","doi-asserted-by":"publisher","first-page":"403","DOI":"10.1146\/annurev-chembioeng-061010-114257","article-title":"Tissue engineering and regenerative medicine: history, progress, and challenges","volume":"2","author":"Berthiaume","year":"2011","journal-title":"Annual Review of Chemical and Biomolecular Engineering"},{"key":"bfab4cc4bib2","author":"Marieb","year":"2010"},{"key":"bfab4cc4bib3","doi-asserted-by":"publisher","first-page":"866","DOI":"10.1007\/s12015-015-9618-4","article-title":"Stem cell differentiation toward the myogenic lineage for muscle tissue regeneration: a focus on muscular dystrophy","volume":"11","author":"Ostrovidov","year":"2015","journal-title":"Stem Cell Reviews and Reports"},{"key":"bfab4cc4bib4","doi-asserted-by":"publisher","first-page":"267","DOI":"10.1038\/nrm.2016.7","article-title":"Molecular circuitry of stem cell fate in skeletal muscle regeneration, ageing and disease","volume":"17","author":"Almada","year":"2016","journal-title":"Nat.
