1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The stem cells involved in renewal of the corneal epithelium are located in the basal region of the limbus, a narrow transition zone surrounding the cornea. In many ocular surface disorders loss of these stem cells results in partial or complete vision loss. Conventional corneal transplant in these patients is associated with dismal results. Stem cell transplantation offers new hope to such patients. The umbilical cord is emerging as an important source of stem cells that may have potential clinical applications. There are advantages to the use of umbilical cord stem cells as these cells are less immunogenic, non-tumorigenic, highly proliferative and ethically acceptable. In this study, we have confirmed the expression of several putative limbal stem cell markers such as HES1, ABCG2, BMI1, CK15 as well as cell adhesion-associated molecules INTEGRIN-α6, -α9, -β1, COLLAGEN-IV and LAMININ in our recently characterized CLEC-muc population derived from human umbilical cord. Ex vivo expansion of these cells on a human amniotic membrane substrate formed a stratified cell sheet that similarly expresses some of these molecules as well as cornea-specific cytokeratins, CK3 and CK12. Transplantation of a bioengineered CLEC-muc sheet in limbal stem cell-deficient rabbit eyes resulted in regeneration of a smooth, clear corneal surface with phenotypic expression of the normal corneal-specific epithelial markers CK3, CK12 but not CK4 or CK1/10. Our results suggest that CLEC-muc is a novel stem cell that can be ex vivo expanded for corneal epithelial regeneration in the treatment of various eye diseases.
