Cuticle Disruption: A Method to Collect Hemolymph from Drosophila Larvae
0 Views •
2023
The Drosophila hemolymph serves as both blood and interstitial fluid, circulating throughout the body during the larva and adult stages. This video describes a protocol to collect larval hemolymph in order to quantify the circulating cells.

The plant cuticle is a waxy outer covering on plants that has a primary role in water conservation but is also an important barrier against the entry of pathogenic microorganisms. In this video, we demonstrate the analysis of plant cuticle mutants identified by forward and reverse genetics approaches.

Aerial plant organs are protected by the cuticle, a supramolecular biopolyester-wax assembly. We present protocols to monitor selective removal of epi- and intracuticular waxes from tomato fruit cuticles on molecular and micro scales by solid-state NMR and atomic force microscopy, respectively, and to assess the cross-linking capacity of engineered cuticular biopolyesters.

Lipid polyesters constitute the structural components of two cell wall modifications, the plant cuticle and suberin-containing diffusion barriers. In this video, we describe a method to depolymerize cutin from whole delipidated leaves. The method can be applied to investigating mutants compromised in either cutin or suberin biosynthesis.

Source: Taylor, M. N. et al. Using Single-Worm Data to Quantify Heterogeneity in Caenorhabditis elegans-Bacterial Interactions. J. Vis. Exp. (2022)This video demonstrates the quantification of intestinal bacterial load variability in individual Caenorhabditis elegans through mechanical disruption. It outlines the steps for sample preparation, mechanical disruption, serial dilution, and colony counting to assess differences in intestinal bacterial load among individual worms.
FAQs
These factors can alter the outer covering through different routes. Abrasion physically damages the surface, chemical exposure changes its properties, and enzymatic degradation breaks down cuticular material. Interference with cuticle formation or molting affects how the covering develops rather than simply damaging an existing layer. Distinguishing these mechanisms helps biologists relate the cause of disruption to changes in protection and permeability.
A more permeable cuticle provides less effective control over exchange with the environment. This can affect water balance and reduce the protective value of the outer covering, leaving the organism more vulnerable to environmental conditions. Because the cuticle contributes to barrier function, studying permeability changes helps connect surface damage with broader consequences for arthropod health and survival.
Cuticle formation and molting are linked to the replacement or development of the protective outer covering as an arthropod grows. Disrupting these processes can weaken structural protection and interfere with successful growth. This mechanism differs from surface abrasion because the problem arises during construction or renewal of the cuticle, making molting-related disruption important in studies of development and survival.
Researchers can examine changes in barrier function, permeability, water balance, and structural protection, then relate those changes to environmental interactions. The process may also provide information about growth, defense, and survival. Considering several outcomes together is useful because a damaged or altered cuticle can influence both the organism’s physical condition and its ability to respond to environmental pressures.
In chemical-toxicity research, cuticle disruption provides a biological context for evaluating how exposure alters an organism’s protective covering. Investigators can focus on whether exposure is associated with weakened structure, increased permeability, or impaired cuticle formation and molting. These observations help connect a chemical condition with consequences for barrier function, water balance, and organismal health.
In pest management, disrupting the cuticle or its formation can be examined as a way to compromise protection, growth, or survival in arthropods. In host-pathogen research, changes to this outer barrier can clarify how surface protection influences interactions with environmental biological agents. Both applications use cuticle disruption to connect barrier condition with vulnerability and ecological performance.
