Background:

  • Understanding pineal gland function requires studying individual cells.
  • Current methods for pineal cell isolation can be complex.
  • Single-cell RNA sequencing (scRNA-seq) offers deep insights into cell physiology.

Purpose of the Study:

  • To describe a straightforward protocol for isolating single cells from the pineal gland.
  • To facilitate the application of single-cell RNA sequencing to pineal gland research.

Main Methods:

  • Incubation of whole pineal tissue in an enzyme preparation to dissociate tissue.
  • Gentle trituration to further break down tissue into smaller aggregates.
  • Filtration to isolate individual cells from the suspension.

Main Results:

  • A simple and effective procedure for single pineal cell isolation was established.
  • The entire protocol can be completed in under 2 hours.
  • The isolated cells are suitable for downstream applications like scRNA-seq.

Conclusions:

  • This protocol provides a vital tool for researchers studying pineal gland cell physiology.
  • The accessibility of this method will accelerate discoveries in pineal gland differentiation, metabolism, and cell-cell communication.
  • This technique is a key enabler for advancing pineal gland research using single-cell genomics.
