Fig 10. Extended structures appear to be early stages of complex formation.

One extended structure is adherent to the outer nuclear membrane (blue arrows) with some internal microfilaments labeled (green lines) and potential core noted (asterisk). A second extended structure is capped by a single membrane organelle that is proposed to be smooth endoplasmic reticulum (SER). The needle-like projection and the apparent cap on the core are unique. An intact gap junction (GJ) is noted, as is a nuclear pore (NP). Day 15 lens about 460 μm from the capsule-fiber cell interface.
