Source: Tay, S. B., et.al. Anti-virulent Disruption of Pathogenic Biofilms using Engineered Quorum-quenching Lactonases. J. Vis. Exp. (2016)This video demonstrates the process of inhibiting biofilm formation by introducing an enzyme that disrupts bacterial cell signaling. The enzyme prevents the bacteria from producing extracellular polymeric substances, thereby reducing biofilm development on a glass-bottomed microdish. Finally, the biofilm structure is visualized using fluorescent lectins and...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell! Since enzymes help control the rate of reactions, their activity is regulated so that appropriate amounts of starting materials, intermediate metabolites, and products are maintained in the cell. Excessive build-up or depletion of...

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure. Competitive inhibitors occupy the active site of enzymes, making them unable to accommodate the substrate. However, sufficiently high...
FAQs
Wound closure helps establish the organized environment needed at a regeneration site. If closure does not occur properly, the injury may fail to support dedifferentiation, cell recruitment, or communication between the wound epidermis and underlying tissues. Studying this failure shows that regeneration depends not only on cell proliferation, but also on creating the correct early wound structure.
Communication between these tissue layers helps establish the molecular conditions that support blastema growth. Disrupted signaling can prevent progenitor-like cells from accumulating or maintaining the regenerative state required for replacement. This relationship provides a mechanism for explaining why an injury may heal without producing the coordinated cellular response associated with regeneration.
The key processes include wound closure, dedifferentiation, cell recruitment, and signaling between the wound epidermis and underlying tissues. Inhibition can arise when one or more of these steps fails to establish a supportive molecular environment. Examining them separately helps researchers identify whether the limitation occurs during early wound organization, cell-state change, recruitment, or tissue communication.
These factors help determine whether injured tissue receives the signals needed for regenerative development. Positional information can guide appropriate tissue organization, growth-factor pathways can support blastema growth, and immune responses can affect the wound environment. Their combined roles help explain differences between tissues that regenerate successfully and those that heal without replacement.
Researchers can examine inhibition as a way to identify which early regenerative events fail after injury. Comparing successful regeneration with outcomes in which blastema development is suppressed can clarify the roles of wound closure, dedifferentiation, cell recruitment, tissue signaling, positional information, growth-factor pathways, and immune responses. This approach connects cellular events with the broader outcome of tissue replacement.
Studying suppressed blastema development helps explain why regenerative organisms, including salamanders, can replace some tissues while other tissues heal without replacement. It also provides context for regenerative medicine by identifying biological conditions associated with tissue repair. In addition, the process may inform strategies that seek to limit abnormal tissue growth by understanding how regenerative growth is controlled.
