Proposed Wording
Some specimens are biological and can contain one or more components including but not limited to cellular molecules, cells, tissues, organs, body fluids, embryos, and body excretory products (source: NCI Thesaurus, modified).

Comments
The sudden introduction of the term "biospecimen" leaves me wondering whether the Specimen resource is supposed to be limited to "biological" products. I don't think so, since the definition of Specimen includes "any material sampletaken from a physical object or the environment." Physical object and environmental testing might look for things that are not "bio." The proposed wording clarifies that not all specimens are biological.
