Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...

Primary mouse cardiomyocyte cultures are one of the pivotal tools for the investigation of myofibrillar organization and function. The following protocol describes the isolation and culture of primary cardiomyocytes from neonatal mouse hearts. The resulting cardiomyocyte cultures may be subsequently used for a variety of biomechanical, biochemical and cell-biological assays.

Source: Matthysse, A. G. Adherence of Bacteria to Plant Surfaces Measured in the Laboratory. J. Vis. Exp. (2018).This video demonstrates the evaluation of bacterial attachment to plant roots using phase-contrast microscopy. Root samples from seedlings incubated with bacteria are first mounted to check for free bacteria. The samples are then washed to remove loosely attached bacteria and remounted using a suitable coverslip to prevent damage. Finally, the number of bacteria attached to the root...
FAQs
Integrins act as cell-surface adhesion molecules that recognize extracellular matrix proteins positioned on a culture surface or biomaterial. When they bind collagen or fibronectin, the interaction connects the cell boundary to the substrate and triggers cytoskeletal anchoring. This linkage helps cardiomyocytes spread, maintain stable contact, and remain suitable for functional laboratory culture.
Collagen and fibronectin serve as extracellular matrix proteins that integrins can bind during cardiomyocyte attachment. Their presence provides molecular recognition between the cell and the culture surface or biomaterial, rather than relying only on nonspecific contact. This interaction supports downstream anchoring and spreading, which are important for preserving viable cells in cardiac models.
Cytoskeletal anchoring converts initial adhesion into a more stable cell-substrate connection. It supports cardiomyocyte spreading and helps maintain the physical organization needed for cells to remain attached during culture. Reliable anchoring is consequently linked to biological outcomes beyond simple retention, including continued cell viability, alignment, electrical signaling, and contraction in laboratory models.
A suitable setup must support the sequence from molecular binding to stable cell contact. Researchers therefore need a surface or biomaterial that can present relevant extracellular matrix interactions, including integrin binding to collagen or fibronectin. The resulting attachment should permit spreading and preserve conditions in which cardiomyocytes remain viable and capable of functional behavior during culture.
Reliable attachment is particularly important when cultured heart muscle cells must remain viable and functional long enough to reveal biological responses. It supports models used to study cardiac development and disease, evaluate drug effects, and engineer cardiac tissues. In each case, stable cell positioning helps researchers examine behavior such as alignment, electrical signaling, and contraction.
Attachment determines whether cardiomyocytes can establish stable contact with the material used to construct or model cardiac tissue. Effective adhesion supports cell spreading and alignment, while also helping preserve electrical signaling and contraction in culture. These properties make attachment a foundational consideration when designing biomaterials intended to reproduce selected aspects of the native heart environment.
