(ˈfɒlɪkəl)
n
1. (Anatomy) any small sac or cavity in the body having an excretory, secretory, or protective function: a hair follicle.

a. a small cavity, sac, or gland.
b. one of the small ovarian sacs containing a maturing ovum; Graafian follicle.

fol·li·cle

(fŏl′ĭ-kəl)
1. A small, protective sac in the body. In most vertebrate animals, fertilized eggs develop in follicles located in the ovaries. In mammals, hair develops and grows from follicles in the skin.
2. A dry fruit that has a single chamber and splits open along only one seam to release its seeds. Milkweed pods are follicles.

follicle

A small secreting cavity or sac. Ova (egg cells) develop in follicles in the female ovaries. See hair follicle.

Dental follicle progenitor cel heterogeneity in the developing mouse periodontium.
This low expression of STRO-1 is in agreement with other reports in PDLSCs, (27) PDL cells, (28) dental pulp and dental follicle stem cells.
Although the aetiology is unknown, it is believed to arise from various sources of odontogenic epithelium like dental follicle.
The soft tissue associated with tooth #17 (Figure 5) was a hyperplastic dental follicle.
In 1980, Gardner described odontogenic fibroma and classified it into three different related lesions namely (1) the hyperplastic dental follicle, (2) a fibrous neoplasm with varying collagenous fibrous connective containing nests of odontogenic epithelium (CODF simple type) and (3) a more complicated lesion with features of dysplastic dentin or cementum like tissue with varying amounts of odontogenic epithelium (WHO type) which was later designated as CODF WHO type.
Incidentally, autologous stem/progenitor cells can be collected from dental tissue including Dental Pulp Stem Cells (DPSCs), SHED, Periodontal Ligament Stem Cells (PDLSCs), Stem Cells from Apical Papilla (SCAP), and Dental Follicle Progenitor Cells (DFPCs) (9).
Five major sources of stem cells have been proposed: dental pulp stem cells (DPSCs); stem cells from human exfoliated teeth (SHEDs); periodontal ligament stem cells (PDLSCs); stem cells from the apical root papilla (SCAPs); dental follicle stem cells (DFSCs) (Table 2, Figure 2).
Mononuclear cells (osteo-clast precursors) must be recruited into the dental follicle prior to the onset of eruption.
