Development of a mutant of Dictyostelium discoideum, HG403, is described whose cells spread strongly on a substratum. Although the mutant cells were less clearly polarized into the front and rear ends, and usually less extensively elongated than wild-type cells, their aggregation pattern was only slightly less regular. Cells of the mutant responded well to cyclic AMP by chemotaxis, although their capability of stabilizing cell shape and maintaining dominance of a single moving front appeared to be reduced. Mutant HG403 proved to be ideal for the preparation of cytoskeletons in which the organization of the microtubular system, the network of filaments between them, the dense texture of the microfilament network at the periphery of the cells, as well as the bundling of microfilaments in spike-like extensions, could be observed.

The Forest of Biologists

We are excited to announce the launch of The Forest of Biologists, a new biodiversity initiative created with support from the Woodland Trust, aiming to counteract nature loss and safeguard some of the most critically endangered ecosystems for future generations. For every Research Article and Review/Commentary article that is published in Journal of Cell Science, a native tree is planted in a forest in the UK. View our virtual forest here.
Propose a new Workshop for 2025

Do you have an idea for a Workshop? We are now accepting proposals for our 2025 Biologists Workshops programme. As the scientific organiser, your involvement will be focused on the science. We'll take care of all the logistics. In 2025 we'll continue our efforts to diversify our Workshop programme and will be reserving one of our Workshops for an application from a Global South (GS) country to host an event overseas.
Editorial: Publishing where it matters
