# Ultrastructure, Polarity, and Reproduction of the Golgi Apparatus

## TL;DR

This paper discusses the structure and function of the Golgi apparatus, proposing a model for how it matures and reproduces.

## Contribution

The paper first proposed the maturation model of Golgi cisternae formation and degradation.

## Key findings

- Cisternae form on the cis face of the Golgi apparatus.
- Cisternae are destroyed on the trans face to form chromophobe vesicles.
- The proposed model is now widely accepted in cell biology.

## Abstract

In this note published in 1957 in the Proceedings of the French Academy of Sciences, the zoologist Pierre‐Paul Grassé proposed for the first time that the cisternae of the Golgi apparatus form on the “cis” (proximal) face and are destroyed on the “trans” (distal) face to form chromophobe vesicles (presumably secretory granules), suggesting a model of maturation of the Golgi cisternae. This model is currently the most accepted by the cell biology community.
