A) DLP bioprinted microarray of cell-laden microgels with controllable geometry and mechanics. Reproduced from [196] with permission. B) Each microgel can be (i) loaded with a co-culture of HUVECs and hMSCs (ii) that self-assemble into (C) pericyte-supported microvascular capillaries in less than 72 h. D) The pre-vascularized microgels can be injected with a built-in vasculature and show ability to anastomose with adjacent capillaries in-vitro. E) These microgels can also be injected into selective regions within 3D printed stackable microcages, to result in complex 3D constructs with predefined tissue regions.
