The phrase "a subset of cord" is correct and usable in written English.
It can be used in contexts where you are discussing a specific portion or category of something referred to as "cord," which could be a type of material or a data structure in programming.
Example: "In our analysis, we found that a subset of cord was particularly effective for the project."
Alternatives: "a portion of cord" or "a segment of cord".
Functional studies in mice show that Dmrt3 is expressed in a subset of spinal cord neurons that are crucial for the normal development of a coordinated locomotor network that controlling limb movements.
However, these high isolation frequencies are often only obtained in a subset of human cord blood samples after applying various critical parameters [ 12].
The lack of a rotarod phenotype is even more surprising in the context of the gait abnormality and that Olig2 may additionally target a subset of spinal cord motor neurons.
Although the sy671 mutants can be rescued for the initiation of sperm transfer using a transgene to drive neuronal expression of UNC-18 in a subset of ventral cord cholinergic neurons (most likely the CA neurons), these animals did not transfer as many sperm as wild type.
While a direct role for LKB1 in MS has not yet been described, in one study (Sun et al., 2011), conditional knockout of LKB1 from a subset of spinal cord neurons produced mice with MS type symptoms including demyelination and macrophage infiltration.
Whole‐blood pheno‐typing by flow cytometry was performed at 18 months and in a random subset of cord blood samples.
This result is consistent with a previous report of endogenous bar-1 expression in a subset of ventral nerve cord neurons [37].
We also observed weak and variable expression in a subset of ventral nerve cord motorneurons.
In a subset of cultures, spinal cord neurons were treated using terminal deoxynucleotide transferase mediated deoxyuridine triphosphate nick-end labeling (TUNEL) and immunofluorescent double labeling as well as Western blot.
In addition, dme-miR-92a, the ortholog of bmo-miR-92, was found expressed in the brain primordium and a subset of the ventral nerve cord in Drosophila [42], implying its possible role in regulating brain and nerve development.
