Summary Introduction

Extracellular matrix (ECM) can be defined as an insoluble mesh-work that is composed of polysaccharides as well as proteins. The components of this matrix can be modified, secreted plus synthesized by various kinds of cells. This structure is present in animal and plant cells. These cells provide additional cues that determine the cell’s activity.

Expert Solution & Answer

Explanation of Solution

The major function of the ECM is to provide structural support to the cell. In plants, ECM is seen in the cell wall. This matrix helps the plant to maintain its shape and turgor pressure serves as a barrier against foreign materials and provides skeletal support to the entire plant.

In animals, the ECM is seen abundantly in the connective tissue. It is mostly comprised of fibrous protein that provides the animal its tensile strength.

You inject morpholino oligonucleotides that inhibit the translation of follistatin, chordin, and noggin (FCN) at the 1 cell stage of a frog embryo. What is the effect on neurulation in the resulting embryo? Propose an experiment that would rescue an embryo injected with FCN morpholinos.
