Smooth muscle spheroids: Superior building blocks for bladder tissue engineering

Congenital bladder disorders in children necessitate innovative approaches for bladder tissue regeneration, aiming to minimize complications associated with conventional therapies. This study focused on generating a cell-seeded scaffold using superior smooth muscle cells (SMCs) by exploring the potential of smooth muscle cell spheroids (3D SMCs) compared to conventionally cultured SMCs (2D SMCs) for bladder tissue engineering. Additionally, adipose-derived stem cells (ADSCs) were investigated for their impact on SMC proliferation and maturation, and pre-differentiated smooth muscle-like ADSCs (pADSCs) for their potential as alternative cell source.
